I don't need either one as my K3 works just fine. The 350 has been resetting about every 2nd or 3rd time I turn it on which makes startup take a long time. But I put up with it because I like the portability. I was hoping to use the 950 for PDFs and landsape reading of ePubs in two-column mode, but it looks like it will be headed back to BB tomorrow as nothing I do can get it to connect. I could still use it, but if it is broken right out of the box then other things could also be bad on it. Since Sony seems not to care since I didn't buy it directly from them, I'll take it back and get a refund.
