Well, you can wait months for a macbook that may or may not have the right technology for you, or you can buy the next gen machines now and even more within a few weeks. Intel just released their i3/i5/i7 mobile chips, and dell, asus, and others already are selling laptops with them. Unless you already have apple computers, you'll be throwing your time and money away for no good reason.
I don't hate macs or OSX, I hate people and statements that portray them as better than anything else. Macs are A solution, not THE solution. Get a good desktop i7 with Windows 7 and come tell me that sucks for photo or video editing.
