A friend and I just made the drive to the closest Sony Style store yesterday--about 100 miles. Store is in Santa Clara, CA. I called before we left and was assured that they had a lot of the 350s and 650s in stock--in both colors. But when we got there, they only had the 650s in red and the 350s in silver. I was thinking I wanted a black 650 but ended up with a red one and am very happy. My friend also got the red 650.
We both got the covers with lights. I really like it--the light works really well! And I love my 650! For me it's just about the perfect reader. Love the easy access of the touch screen interface and absolutely love the dictionaries. I'm coming from a nook, and I basically quit using that dictionary because it was such a hassle. I haven't tried taking notes yet--but that's not something I'd do a lot of anyway.
We also bought a 350 for my Mother in Law. We're going to load it up and then send it to her. I really like that one too--love the small form factor. I'm almost considering sending her the 650 instead!
