I've been in the market lately for an epub compatible reader and after doing all the same window shopping I had done before getting my K3, I've chosen the PRS-350. The silver was/is a minus for me also, but that shortcoming doesn't amount to the shortcomings of the other readers I had considered.
If the silver doesn't prove to be too much of a distraction, I'll just live with it. However, I'm getting keen on the idea of a skin and may wind up buying one just to have it. I'll probably go for something black or a nearly black British racing green.
However it goes, after doing a few pretend touchscreen page flips on my Kindle last night, I'm know I'm ready either way.
