Help Me!

Ok, so I was on Apple’s website and saw that they had $1800 Macbook Airs for $999. Being how easy it is to click a mouse, I ordered one, but now I’m having buyer’s remorse. 1. Most of the stuff I do is on the PC and I just got this kickass HP laptop. 2. I want to do some iPhone development, but will I ever find the time? 3. Maybe an iMac would be better, since I don’t really need another laptop.
