Not sure where this should be posted, so I'm posting here... Anyway, my mum is computer-illiterate and I just started teaching her today on an old Toshiba laptop salvaged from a computer shop because it was declared abandoned (left for 6+ months). Unfortunately... the laptop is a piece of shit, battery doesn't even last an hour, the original charger is missing (using a charger that only works when the computer is off due to being half the wattage the laptop needs), and corners are broken and it looks like someone jammed a butter knife into the card reader and had a good old time twirling it around and the pins are just destroyed. But I digress... She has an iPhone 3GS (which is due for replacement) and she seems quite competent in using that, so I'm wondering if getting her a MacBook Air would be a sensible way to go, as the usage conventions are quite similar (mail apps are broadly similar, scrolling, gestures are the same etc), but their entry price leaves a lot to be desired when one could get a cheap laptop for half the price, although I do realize you pay peanuts and you get a monkey. We can afford to get one, but it would be difficult justifying the expense. But here's the problem... I have no idea how to use OSX. I've never at any point owned a Mac (owned iPhones for nearly 4 years though), but I'm sure that if I took a week to familiarize myself with it, I'd pick it up pretty quick and thus would be able to show her the ropes, too. Is OSX really that different to Windows? Or should I still consider a PC for her? Any ideas are welcome. Cheers.
