It's exactly making a go-kart and calling it a Porsche. All phones, tablets, MP3 players, laptops, netbooks, servers, desktops, and mainframes are computers. It's the size and the power that differentiates them. The OS is merely the transmission and the device features are the optional extras.

The N900 is a very good smartphone - more smart than phone but that's not a bad thing. It's not a pocketable, general purpose, personal computer. There are such things. The Viliv S5 and UMID BZ come to mind.

If you still think the N900 is a computer, check out a more open, more standard, and significantly cheaper computer that just went on sale for $99. It's the NanoNote which has copyleft hardware, the full Linux Kernel, and the OpenWrt Linux distro.

The only thing to recommend the N900 over the NanoNote (or the Viliv) is the phone capabilities and that is the N900's distinguishing feature. Frankly, just as anyone who bought an N900 expecting an iPhone bought the wrong thing, so did anyone who bought the N900 as a mobile computer.

It's a great smartphone. Accept it.
