Tablet PCs are only useful if you inted to do a lot of notetaking. For Web browsing or listening to much they are no better than traditional laptops.
Only the handful of HP tablet PCs have touchscreens, otherwise they are all standard screens.
There are many online retailers which have tablets and PCs for sale. For instance, an individual may purchase a tablet and a PC from Amazon, Best Buy online, Fry's online, and even eBay. Additionally, a person may purchase these products from the online store called New Egg.
A laptop tablet is a device smaller than a laptop but with the added benefit of a touch screen, such as an iPad. PCS stands for personal communication services, a wireless internet service that will enable you to connect your laptop tablet to the internet.
