For the Apple critics: I know they're irritating, try to trap you into their systems with deliberate incompatibilities (plugs a different shape, upside down, no USB link on the ipad, silly iTunes for standard data transmission, etc) but after 20 years of Windows then Android, I just bought a Macbook. Not a religious experience, but wish I'd done it sooner. To compare it with a Dell or HP (or Chinese cheapie Android - which I've just given up on .. lots of fun to fiddle, but 3 out of 4 gone back in 3 weeks with hardware failure) is to compare a Lucky Star with a Merc. It's exquisitely built and WORKS. The OS is wonderfully integrated and sensible. Could do without some of the cutesy wobbly icons as I brush over them, and the probably-doomed-but-your-stuck-with-the-ports tricks like "Thunderbolt" ... they're bearable. Hate to admit it, but it's worth the price. And with slicker cofunction with Windows, easy double boot, easy bootup from attached HD, etc. .... you can easily have the best of both worlds. No wonder it's doing well. MS has lost it.
Google's Android is rubbish beside Apple. What makes it fun is what makes it makes it not fun ... everybody having a go, and no one in charge. I wouldn't buy a car put together in a backyard from a hundred bits from here and there, but for years I've been buying computers like that. The fun is over. If your crap car crashes you're in strife. If your crap computer crashes it's not fatal ... but ENOUGH!
