There are currently two eBook readers fighting for domination of the high-tech literary scene: the Amazon Kindle and Sony's line of readers.
There's about to be a third:
The iRex Digital Reader 1000S boasts the largest screen of the bunch at 10 inches and even uses a Wacom touch surface as its primary input method. It doesn't have a 3G card like the Kindle, but it's definitely got a lot of tech inside. It does, however, retail for a suggested $750..
The Kindle runs around $360 while the Sony's run from $300 to $400 depending on the model. While many people avoid reading nowadays, an eBook reader is a great high-tech way to get your literature on.
The iRex does not have access to an eBook store, but will display many formats. Amazon and Sony both have eBook stores that work for their respective devices.
Personally, I own this Sony eBook Reader and absolutely love the thing. It's simple and does what I need it to do: display books. The Kindle's 3G and keyboard is fun and all, but I'm not an impulse book buyer. I don't need to buy books on the go. The Kindle's internet features are redundant for iPhone owners like myself and the battery life is much lower than the Sony.
This iRex reader just feels like overkill. A 10" screen seems great, but that's pretty large for a convenience device. The Kindle and Sony's are sized well and can easily be tucked into a laptop case or small bag.
Do you have an eBook reader? Which one?
