I'd make more selling it to anybody but my nephew, but I'm not really interested in upgrading at this time as I'd rather pay off the debt (the car gets paid off next month - woohoo!).

I have a film from Photodon on my MBP. Works fairly well, though not as good as if the matte were built in. Before I put it on, I moved both of my air cleaners into my office and let them run overnight. Worked well to eliminate dust.

I'm also open to getting a Mac Pro so I can supply my own display - though I don't consider that an option until after they've upgraded them with Thunderbolt. Per MacRumors the next MP is about a month overdue (based on average days between updates).
