I think my N900 is actually going to save me money. It's the first phone i've purchased sim free and I feel no desire yet to look for a replacement, i've not had it a year yet and still absolutely love it. I won't go through what it does for me or what it replaces as that subject has been covered many times, but, when i do feel the gadget wanderlust i'll probably go for an N9, which will be a year or so old by then, cheaper, and i'll know how well (or not) supported it is.
Yippee :-)
