I just got a used Rev A 1.6/80. Its about a year old so it's certainly got a bit of wear and tear. Has maybe 15cm of screen wobble, measured from the top of the screen moving back and forth. I'm probably going to have a load of questions so I'll keep it to this thread, along with any impressions I have etc. First thing I noticed was that scrolling in firefox was really jerky. Is this pretty normal? You'd think it could handle it fine, I don't remember experiencing jerky scrolling on machines quite a bit older then the Air. After looking a bit more I'd say it's perfectly fine on the 13" but running a 20" its reaaaly choppy. Seems slower then I would have thought. The hard drive is the main slow part and that shouldn't have much to do with scrolling an already loaded web page without anything else open. And the graphics are integrated but not that slow.. proc is slow but again it doesn't seem to explain the jerky scrolling. I did originally get this with the intent of reselling it, then decided maybe I'd just keep it as my main computer. So i'll give it a try before moving up to an Alum Macbook.
