My MacBook Air has never failed me. I've had it for nearly two years and it's my baby and I love it. I also love my MacBook Pro. I bought my first iBook when I was 16, and since then have had two MacBooks (hard-drive fails, both of them), one MacPro (had it for five years, then I moved and it stood gathering dust for a year and when I got home and turned it on the motherboard got fried, so, my own fault) and now these two laptops. I love MacOS. I have no desire for any other devices, though it's likely I'll get an iPhone when my old mobile dies, given that it'll be compatible with my calendar and address book and everything.
