I agree the 64M of RAM is a big weakness. I have no idea why they didn't make it 128M in a device at this pricepoint. I don't think the price differential would have been all that much and it would have been a nice touch.

For the record, I haven't really found the 4705 to be that bulky, but then I don't have much to compare against except my Zaurus. I'm still so smitten by the video quality that I have not been put off by too many of the other issues yet. I think I can say that the NavPad was a terrible idea though. Not sure why they didn't just use hard button cursor keys. When you have a touch screen display I don't know why you would want a trackpad (fingerprints is the only thing I could come up with?).

I'll do a full review probably next week ...
