My dreams are simple and don't rely on any not-invented-yet parts:
15" Macbook Pro with 1920x1200 LCD, trackpoint (aka "nipplemouse"), and TWO BLOODY MOUSE BUTTONS FOR THE LOVE OF ALL THAT'S HOLY.
That is all. So, so tired of Apple's insistence on crippled LCD resolutions and single-button mice. Yes, I know about the two-finger right click, no I don't think that's sufficient. Trackpads suck to begin with compared to trackpoints.
Unfortunately for you, most people don't agree with your sentiments, and Apple are unlikely to offer options on either front.
