the nook also fits your requirement, if you have a Barnes and Noble or a Best Buy near buy you can go and play with both.

the big difference is wireless and price the 650 is a rather pricey unit for no wireless the nook can be had for $149 wi fi only and $199 wifi/3G

I like the barnes and noble bookstore platform alot better than Sony's.

both are the two best in hardware in my opinion. Both are gorgous ,both have touchscreen (the nook being the second color LCD screen) both can do ePub with or without Adobe Digital, both wil do PDF's, though I think the Sony 950 (the 650's bigger brother) is the leader in the eink department for Pdf's.

Now another option for you, if reading on an LCD screen does not bother you, is the nook color, which is about the same price as the Sony 650. It's a full color touchscreen LCD captactive screen eReader that is also wireless through wi fi. It not only fits all your needs but will excel in many of them as well and has features that eink either just can't match or does not have. .

Especially notes, highlighting ( you can highlight in different colors for color coding) your notes have sticky's than you can hide or show, It really is quite the featured packed eReader. Especially for notes, annotations, highlights, etc plus the ability to tap a word and have a Google Search, WikiPedia, dictionary options pop up. You can also share passages with people on Facebook or Twitter or email.

But again that is if reading on an lcd doesn't bother you. I thought it would with me but after some tweaking of the settings , I'm actually enjoying this better than eink because of the sharper contrast.
