Comparing the Processors and the Ram (performance) of various mobile computing, Strangely the I-phone outperforms most E-readers at 800Mhz (G3S) while most E-readers (6inch) are at 532Mhz (They don't like showing their Mhz and force you to go to the manufacturer's specs to find out).
Even the Huge (with a letter size screen) iRex Digital Reader 1000s is just a measly 532Mhz and Just 128MB ram (which is Half the ram of smart phones) at $750. No wonder it is so slow.
Compared to the stats of a Tablet Netbook (which folds up to become a slate) at $500 performing at 1.6Ghz, 1GB Ram, with an 8inch screen, wifi , blue tooth, a camera, and modifiable memory your GM. Check out the model Asus Eee PC T91.
For the Tech Savy GM out there get the Tablet PC (netbook power). The price range is $400-$800 and is perfect for reading your PDFs, running your game (and dice programs) and keeping all your maps on file instead of printing them out.
Anyway I've researched and checked all the other tablet PCs they are all Laptops with Tablets, so they all cost at around $1300-$2000. Only the Asus's PC T91 is a Tablet Net-book.
