For hackers it's fine; my Pandora is less than 1 ghz and I use it every day for a lot of things. Yeah I cannot really do that fancy smancy cpu/gpu killing web stuff on it but for nicely built apps and console work it works really well. For devving too as that's what I do mostly on it. If this thing runs linux well if would add nicely to my collection of small devices that can. I never had a N900 and I don't really use a phone for calling, but I do collect internet capable, linux capable devices and I use them a lot.

I think the hacker market is large enough to sell out at least a few batches of this thing.
