Do not get an N900 (Can we have flashing lights icons)
The Register review was a poor review. You would be more of an idiot to go down that road. It is filled with complaints, begging forums and hating Nokia with all you can, for releasing such a dire piece of hardware.
The N900 is seriously a huge pile of steaming turd, and to anyone thinking of getting one read the forums. http://talk.maemo.org/ (Ignore the fanbois)
It can't MMS (send or receive), it can't mail sync, it can't mail for exchange, can't assign ringtones to contacts, conversation view only, it can't use the on board video camera for video calling (no software to run it) it doesn't tell you if you missed a call, or got an SMS (you need an app). Build quality on the charge socket is dodgy, phone voume is poor (software bug) file manager is poor (can't double click to load) poor music player, no app store. No sat nav, no geolocation (Ovi maps is poor) no voice direction stuff, Keyboard is badly designed. (Headphone jack sticking into your palm) The kinetic scrolling is twitchy, no word editor yet available for the platform, free or otherwise. Win7 doesn't like it (Ubuntu and XP loves it) Nokia have pulled the plug on Maemo, in favour of Meego, support as a result disappeared.
It truly is the shockingly awful and Ebay prices are plummeting, I can't even get half what I paid for mine. Get the HTC desire, I wish I had.
Otherwise, Booo on HTC for being a sell out. (I would still get an HTC desire.)
