For the last couple of Years I have been using a Sony PRS-505 E-book reader and enjoying it greatly however over hte past few months the battery life was dropping to the point where I was having to charge it daily.
So I finally decided to upgrade to the new Sony PRS-650 and boy am I glad I did and wishing I upgraded long ago.
The PRS-650 has a touch screen, I wasn’t to sure if I would like this or not but it works well and does not affect hte crispness of the screen as did the PRS-600 or 700 units.
THe Screen is the new E-Ink Pearl screen with 16 levels of Grey vs 8 in the PRS-505 and seems much crisper and the whites are whiter.
The new Models from Sony Both have 2GB of Storage VS 256mb in the old PRS-505. So unless you have a bunch of PDF files you need to keep on the reader you have plenty of space.
The PRS -650 includes the dual Card Readers and MP3 Playback ability of the PRS-505 while the POCKET Version PRS-350 does not.
On my PRS 505 I needed to use a Memory Stick to Store the books on as the system did not have enough storage, Now I have plenty of room and Still have both card slots available for Expansion.
The Sony Reader’s in General are more expensive than the other brands however the fit, finish and solid construction in my opinion are worth it.
A Good friend purchased the Kobo reader while quite a bit cheaper and having the same E-ink screen it is much slower and does not feel as good in the hand. Also the Sony’s have cases that make them more book like (A Cover that flips open to the side.) Where the Kobo has only a slip case.
I still Use my Ipad for PDF Files but for all other reading the Sony PRS-650 is Great.
