Google really needs to be thinking further ahead. Since they're not interested in decreasing car-based transportation (imagine if they spent all that money on a first world train system), then with climate change and rising sea levels, I suggest they get into self-driving boats. And nanotech sunscreen.
In the "mine is older than yours" category, I still program on a mid-2007 15" MBP! I recently upgraded it to 6GB RAM (I don't know why I waited so long), but I now have those vertical lines on the display that are from the internal connector (or something similar). Drat! Now I feel dumb for upgrading the RAM. The machine isn't bad, but replacing the screen is a no-go given that I could buy one on ebay for the price of a replacement screen. And I agree re: new ones' not being upgradable. I'd rather have a relatively bulkier form factor that's hackable, but Apple disagrees. Also, $2K is a lot for me.
