I just used an iphone recently for the first time. I'd so buy one if they supported third party apps, like SSH. The responsiveness in the UI is absolutely amazing. And the multi-touch is nice too.

So, IMO, the n800's market has been reduced to those of us who want to install third party apps as the ipod touch seems to be in direct competition with the n800 in every other respect. I suppose the n800 still holds some VoIP market potential too, but without SCO Bluetooth headset support, it's probably rather limited.

The n800's successor could compete, but it would need hardware 2D drawing support (and it would need to make heavy use of it in the UI) or a GPU to keep up with the iphone's interface, IMO. Currently, SDL draws with screen tearing on the n800 and it doesn't seem to support hardware accelerated 2d drawing as it's rather slow.

A GPU would be wicked sweet. And SCO and A2DP bluetooth audio built in to the firmware would be quite nice too.
