I have to admit the macbook air fever has gotten to me. however I already have an iMac and a MBP. I can't bring myself to get a MBA because i really don't want to part with the MBP i really use it for work, design, music, film and such and I don't think I can do that with a MBA without some serious power sacrifice, and for me there's also the issue of HD space. Even if it could run all my programs without sacrificing performance the mere space after installing the programs i use would leave me with nothing. If i could upgrade it, it would be even more appealing to me. So for me it would be a third machine, something to carry around the city on a daily basis for mild surfing in a coffee shop or something, but for that purpose it seems to expensive to me. That said I still want one, but I'm hoping the 'Honeymoon' period will pass. Anyway It got me thinking because there are others in my situation with a desktop and laptop and MBA. How many computers do you guys have for one user? How has adding the macbook air affected your other computer usage?
