Hello, I am fairly new to the whole Apple/Mac stuff, and being a GNU/Linux guy for several years, I've lost track of what buying hardware actually involves. My current laptop is a 2005 1.6 GHz Centrino and it runs everything I need in my daily use (text, internet, media). However, I'd like to do record and edit some music, and there it encounters its limits. Effects processing and mixing down 8 to 12 tracks make me grind my teeth. I have experienced the Garageband software and it is pretty neat. The whole user experience I thought I wouldn't care for is actually also quiet... entertaining. So I'm considering buying on those Macbook Air, hoping that the SSD and i5 processor will get me the edge I need. My question is : since there are always new releases of Apple products, is it safe to buy the one that just comes/will come out or is it more sensible to choose a previous model of which possible flaws have been then worked out? If so, is the current Macbook Air a safe choice, i.e. does it have problems? I've notably heard of some wireless troubles, cracks, weird stuff... Also, can I dual boot Linux on these machines ? Happy computing everyone!
