This is almost exactly me, except I have the 17-inch model.

Also dual-boot Ubuntu/Win8, though Win8 is just for games they don't have for linux. I'm a developer and 95% of time is spent in linux.

I find my 17-inch model is a little too large sometimes--barely fits in a backpack. But it's worth it when I sit down to code.

I think portability is the reason why I opted for the 15-inch model originally, but in the end it seems that I don't carry it outside that much. However, I can assure you that you made the right decision if you're using it for work/programming, it was a bit difficult at first to get used to such a high resolution on a 15-inch screen.
