In terms of time, it's a measurement of the TIME it takes LIGHT to cross a certain DISTANCE. Hence, a year in the term "lightyear" is accurately describing distance relative to light travel. Any effect of gravity would still effect both the time of light travel over that same distance of travel so that relativity is still describing a distance.

Effectively, a lightyear is a measurement of distance.

Getting back to the OP, can't say I haven't thought about doing the same. I'm only holding out hope for MeeGo on my N8x0 as a taste of what it might be like on a more MODERN piece of hardware. I'm pretty much done with Nokia, I think. Wasn't done with Maemo on my N8x0 but maybe I should be. I keep getting asked why I'm still here and it gets harder to want to stick around and participate. Good luck, man!
