Casual I would think. Anything more than casually using a computer is a pain on Windows 8 (Or any other tablet software for that matter) and that would always restrict you.
I would also have to look into how well those detachable keyboards are. If they are a pain to type on that could make a difference as well.

Why would your computer not boot up?
if you're using Windows, just insert a recovery disc and a lot of time it will fix it, if that doesn't do it , clean install, sometimes the hdd could have a problem not related to windows at all but sometimes they will just not read right and need to be reformatted.
When Windows fails to boot it is normally caused by a user installing a program or device and it has caused a conflict with one or more other programs. This will no doubt give you plenty of heartache if you're not certain which program caused Windows to not boot up.
If you recently installed a program or application and know where it was installed,you may be in much better shape as for as correcting the error. Here are common ways to correct the problem of your computer not completely booting up or not booting up at all.
If your computer will not boot-up at all,hopefully you have made a good emergency boot disk. You can always make a windows startup disk by creating one from another computer running Windows 98 or Me. Perform the following if your computer won't Boot-Up At All.
FIRST: Put your boot floppy disk in the floppy drive and turn on the PC.On some computers, you may have to access the bios and select the Boot priority to your A: drive. Save any changes and select "Start Computer without CDROM support" and press Enter. Once you are at the A prompt,type dir c: and press enter.
If your programs and other files are present,try restoring your system Registry by following the steps below.This may repair Windows,the Config. Sys and autoexec.bat files to where the PC may boot up normally. When the files are present, it's a good indication of a good hard drive.
SECOND: To correct the problem of your computer not booting up,type in "fdisk /mbr" and press Enter to restore your master boot record.Type "Scandisk C:" to check the hard drive for errors that have occurred. You can also type "Sys C:" to hopefully restore files needed to boot up your computer.
THIRD: If the above procedures fail to repair your computer,you can repeat the first part of step one above and select "Start Computer With CDROM Support" re-install Windows.
Making A Windows XP Bootable Floppy Windows XP users should create a boot disk now by placing a formatted blank diskette in the A: drive, open Windows Explorer to the C:,select Tools,Folder Options ,show Hidden files and and folders,then View Tab. Now you uncheck "Hide Protected Operating System Files (recommended). You will see a warning and click Yes and click OK. Copy the files ntldr,ntdetect.com and boot.ini onto the disk. Remove the disk and label it the Windows XP Boot Disk.
After making your boot disk, recheck "Hide protected operating system files and folders (recommended)" in the Folder Options dialog box. To use the disk when Windows XP won't boot,place the disk in the drive,and unto re-booting,the computer, Windows simply bypass the basic boot files on the hard drive and continue to boot up.
If The PC Won't Boot Past Windows
FIRST: If your Operating System is Windows Millennium,turn on the computer and immediately press and hold down the CTRL key. Once the startup options appear,release the CTRL key. Select Safe Mode and press Enter. You are now in Windows limited version. If you know what caused your computer not to boot,you can now either change or delete that program.
SECOND: Repair your Registry by selecting Start,Run and typing "scanregw /fix" and press enter. This will fix any damage done to the Registry. You can also restore your registry which replaces your current registry with an earlier copy that was backed up by your computer. Click on Start,Run and type "scanregw /restore and press Enter.
To repair your Windows 98 Registry,hold down the CTRL key as you start the PC and select "Command Prompt Only". Type "scanreg /fix" and press Enter and "scanreg/restore" to restore a previously saved copy of the Registry.
If you have Windows XP,press F8 after rebooting the PC should Windows freeze while booting up. You can select "Last Known Good Configuration" after rebooting to allow the computer to boot the last backed up files.And you can choose "Safe Mode" to remove any files you know caused the operating system to hang up.
Be prepared when your operating fails to boot. It would be a great idea to go over this article a few times and print it. Make yourself s notebook and place this and all related articles there.
If your computer fails to boot or begins to become unstable,you can refer to these articles to make corrections that are needed. Learn these steps from your television set with the PC Super Pack.
Be sure to note any changes you make to your Registry and if you're not sure,its best to find a friend that's PC savvy first. Above all,be certain you backup your registry before making any changes and know how to restore as well.
First things First: PC is not booting up, not even BIOS is shown:

Remove all the add-on cards and have only a single RAM (if you have more than 1).
Reset the BIOS (check motherboard manual).
Try to Boot.
Watch for Motherboard beeps.
Have a POST guide and try to figure out the post code.
If BIOS is OK and problem with Booting of Windows/Mac/Linux see above.

What are the similarities between Windows Mac and Linux operating systems?
Windows, Mac OS and Linux are all operating systems. All three can be used in computer desktops, laptops, netbooks, notebooks, smartphones, tablets, etc. You can use any of the three to surf the web, check your email, video chat, as word processors, video editors, for music listening, recording and production, graphics design, and the list goes on and on. However, the software that you use to accomplish the tasks I mentioned might be different depending on which operating system you're using. For example, to go on the internet you a need a web browser: Windows PCs come standard with Internet Explorer, Mac PCs come with Safari, and Linux usually comes with Mozilla Firefox, Google Chrome, or an offshoot of the two (Iceweasel, Chromium, etc).

The best tool to verify that hardware components installed in Windows are working properly is the Device Manager. It provides a comprehensive overview of all hardware devices and their status, indicating whether they are functioning correctly or if there are any issues, such as driver problems or conflicts. Users can also access properties for each device to troubleshoot issues or update drivers as needed. Additionally, Windows Performance Monitor can be used for more detailed performance analysis of hardware components.
What two things do you need to do in order to be able to log onto a LAN?

When do you use the Bcc field in an email?
http://en.wikipedia.org/wiki/Blind_Carbon_Copy
Use it when you're sending an email to more then one person and you don't want the other people too see everyone else that you're sending it too. E.g.
To: Bob
CC (carbon copy):Joy
BCC: Fred
BCC: Kim
Bob can see that the email was sent to Joy, but no one else.
Joy can see that the email was sent to Bob, but no one else.
Fred can see that the email was sent to Bob and Joy but doesn't know that it was sent to Kim.
Kim can see that the email was sent to Bob and Joy but doesn't know that it was sent to Fred. BCC stands for Blind Carbon Copy. Any email address that you put in this section will be invisible to anyone else who receives the email. BCC is very helpful if you want to send an email to a large list of people and you don't want them all to see who else is receiving the email. Another use: I want friend A to see what I am sending to friend B but I don't want friend B to know that friend A can see the message. Therefore I would put friend B in the "To:" section and friend A in the "BCC:"section.

What is the significance of file formats and file extension?
File formats and extensions are more or less the same thing. Their importance lies in identifying how to use the file. That is, having a document with the extension .doc or .docx tells the computer that the file needs to be opened using a word processing application. If the file extension (the .XXX) is .jpg for instance, the computer knows that it is an image file and that it should open it with an image viewer.
I hope this clears things up for you.

WHAT ARE affect displays examples?

it really works....
Windows & was named so because it is the 7th version of windows. And I guess it was the lack of creativity from MS that they couldn't come up with a more decent name :)
yeah i m agree with second line..
but they are following version names after window NT , all windows either XP or vista all have version name.
