The Nook Color has been one of the most successful tablets in the US, snagging a reported 50% market share in non-Apple tablets. I've reviewed it after I got it and wrote a few weeks back about Barnes and Noble's attempt at attracting developers to build or publish their apps in the Nook app 'storefront', but now B&N finally released the 1.2 update. Of course the Nook Color is probably the most easily hacked tablet, being that it flashes ROMs without even installing clockwork mod as it boots off micro SD cards automatically, but if you don't want to void the warranty or deal with the process, read on past the break for more info.
The 1.2 update brings a bunch of features to the table that make this a proper tablet, not the eReader it started as. There's Flash 10.2 in the browser, a proper email client and an app shop that, though limited still, has access to Angry Birds and Pulse, as well as many other popular apps. B&N also built a thing called Nook Friends, a social network of sorts you can use to lend books or get recommendations from friends about what you might like to read.
