I'm certainly no huge expert but I'm willing to help out as much as I can. It would help if you could give people an idea of how much you want to spend.
Since you don't have a smartphone, the Samsung Galaxy Note is something you should consider (somebody else recommended it in the original topic). Light, good screen + it will do everything you want on wifi
and 3G. Its just very, very pricey.

A cheaper option is the Acer Iconia Tab A100. Wifi only, shorter battery life but otherwise a very nice little tablet.

You can go even cheaper with the Lenovo Ideapad (wifi only) with an older version of the android OS but again, it should take care of all of your needs.

If you're not in a huge rush, there will be cheaper, better options down the road, just not sure when or what.
