|The iPad - a pocket computer|
|The Sony - a dedicated eReader|
As you can see they have placed the iPad in amongst all the other dedicated eReaders - all of the other devices listed are eReaders and use the eInk technology. The iPad then should not be considered if you are looking for a device solely for reading eBooks - mind you, the iPad is excellent for digital comic books.
Just wanted to clear that up - it may be picky but it annoys me to constantly see the iPad marketed as an eReader. I love my own iPad but I know if I tried to read a full length novel on the thing I'd be heading for Headache City.
