People usually come to this forum to report problems and look for solutions. Occasionally, some need reasons to justify their decisions NOT to buy MBAs. I don't think it's fair, and I want to tell everyone that I have been very very happy with my MBA. In fact, it is the dream machine that I have been waiting all these year since I switched over to Mac OS (panther). To me, a true portable laptop should be less than 4 pounds. My first Mac notebook was a 12" powerbook. It wasn't heavy, but not light either. However, Apple discontinued it when migrating to Intel. The G4 processor was getting too slow, and so I had to get a Macbook. Macbook was surely a good-value laptop. With 4 GB of ram, my powerbook was no comparison. I was happy with its power and value, but my only complaint was the weight. During the time I have my Macbook, I've always missed my Windows days when I owned a Sony ultraportable. I have seriously considered hacking a Sony to run OS X, and desperately hoped that Apple would come up with an ultraportable one day... then they announced the MBA. I was a bit disappointed at first that the MBA had the same footprint as the macbook (I wished it was smaller). However, I had to buy it. I didn't even care what's in and not in the MBA, I just couldn't wait to lose 2 pounds off my briefcase. After I owned the MBA, I started liking it more and more. Apple's choice of going with the 13" screen and hence the larger (macbook) footprint was actually a good one. I am very happy with the screen. The heat issue - to me is, "What heat issue?". I don't think my macbook ran any cooler than my MBA. All laptops (computers) run hot under stress - that's the law of Physics. May be I am lucky, I never run into core shut-down issues. I admit that I'm no software or graphic engineer. I use my MBA as my sole computer for office and internet use all day (1.6 GHz, 80Gb HDD). I also rip and convert movies from time to time, no problem. The computing power is sufficient for my needs. I connect it to an external monitor when I use it on my desk, and I take it with me where ever I go. Couldn't be happier. Anyone else care to join me in sharing your happy thoughts?
