Do you want an ereader or a colour HD tablet with full wifi access? The Kobo arc comes in 16 and 32gb and is an ereader too, but you can pretty much use it as you would your laptop except for word processing.
There is also the Kobo glo ereader, also full wifi access to either home or open zone , it has built in games, soduko, chess and also a notepad. It has up to 1 month battery life for reading ,access to 3million plus titles including 1million free titles, it auto upgrades and so no need to buy a new device, a built in glo light that glows up the screen and does not spot like some other ereaders, you can buy books using your debit card but also purchase gift cards in store which means you don't need a debit card.
If you want a tablet the Arc is fab, I use it alot, it is very fast and has a great HD screen, twin front speakers, front camera, microphone. Really good for accessing the internet when you are out and about and can pick up free spots, but good at home when you don't want to have the laptop on. it's a great ereader too. wifi connection is free as long as you have someones password, it connects and then remembers the code and so will automatically connect nxt time you turn it on at that location. I have synced mine with my laptop and it has all my forefox bookmarks already in there now. it used android latest version, jelly bean 4 i think, and i have all sorts of apps on it, i watched big bang theory last night in bed on TVcatchup.
