the DRM and limited book titles available...

What file formats does it accept?

A book reader without books?

"The PRS-505 features the same 800MHz Intel Celeron processor, 128MB of memory and 20MB hard drive that its predecessor had. Once again, the device has a battery life quoted as around 7500 page turns and promised to ship it with at least a USB 1.1 or faster port. The latest model comes bundled with an external CD-Rom drive."

Um, something tells me these are the _minimum_ system requirements for the _PC_ it is to be connected to, _not_ the reader itself.

would seem to give the impression that these are features of the unit itself by not clearly putting them under a heading like "System requirements", the use of phrases like "RAM 128 MB Minimum" and "Processor 800MHz Intel® Celeron® class processor or better" offer some pretty big hints that whatever we're talking about is upgradeable through something _other_ than Memory Stick and SD card slots ;).
