Well, I just purchased my second N900 a couple of weeks ago. Like others here have said, the likelihood of something as good as the N900 being available any time soon is low. The N900 software ecosystem is still growing. We have excellent new apps still appearing and the CSSU is going strong and doing well. And, for $350 the N900 right now is a steal. With two N900s (one of them fresh from the repair center with a repaired USB port) I am all set for a few years. It does all I need and more.

PS: It wouldn't surprise me to see Flash 10.x support on the N900 eventually. This community is awesome.
