YES,YOUCAN HAVE MORE THAN ONE PLAYLIST
yes
No. After you pay the one fee to download it, you don't pay anything else, even for updates of that app.
You can Jailbreak your ipod and you get an app that lets you sort you apps/games.
You could use iBluetooth by MeDevil, it does cost 4$ however
The Pandora app can play a song more than once in the same day.
All i can say is you get way more than you pay for, i got an itouch 2 days ago and had never used one before but had heard that they were awesome from my mates and so when i saw they were on special at currys (£150 +free charger worth £25 +£15 ituned gift card for free) i rushed online and got one, i knew my way around it instantly, it is so light and slim. and i prefer to txt people rather than talk to them and so on the itouch you can get an app which is free called textplus and you can text for free and receive messages for free on the itouch. and it has got millions of apps to chose from its amazing i would advise you to get one it does not have a camera that you can take pics with outside the itouch but it has a camera that you take pictures of what is on the screen and it also has bluetooth and wi-fi.... they are awesome.
Yes :)
One good app might be Doodle Jump. It is very simple, and widely popular.
A laptop as you are able to work properly on it as unlike a itouch it is more of a Entertainment device but a laptop is a work device and entertainment device in one and by far the laptop is more compatible maybe you might be intrestested in some of apples other devices such as the macs you can more than likely get a deal on getting a mac and a itouch at a reasonable price check your nearest apple store.
I have the newest one and it doesnt have a "Heating pad" And the new ones have more than the old..so And i have the New one...Hope this helps!
The most recent iTouch is the iTouch 3rd generation, which is the newest one available.
