Here's (allnetdevices.com)
another web-news confirming the Treo600 screen resolution .... yucky 160x160.
But.... come to think of it, the reports are saying that the screen physical size is smaller. That would make the screen pixel to be smaller and closer together. Logically that could make the images on such screen sharper. Well, have to wait for the actual Treo to reach Malaysian shores and see the screen first hand.
