I got my Xperia X1 from http://mobiles.co.uk (part of Carphone Warehouse) and am keeping on eye on them for the N900 too.

I am hoping I can sell my Xperia to go towards getting the N900 as I am sick of Windows Mobile, its too unstable and seems to seriously lack in apps. I even tried writing my own but every time I found something useful it was not available on the mobile API, really annoying.

I am hoping Maemo is more a case of "if its available on Linux, its probably available on the N900" especially as a lot of useful stuff is command line only so would only need a simple GUI written to make it usable by touch.
