Re: kid's toy turned into a proper tablet computer
They just work(tm) and tend to last quite a long time, both build quality and SW updates.
Bought SHMBO a MacBook-Air about 5 years ago and haven't had to touch it - best $1000 ever spent.
Used to get them for salespeoples. If it breaks, walk into a iStore in pretty much any city in the world, get it fixed or swapped, data automagically iRecovers from iBackup and they are back out on the streets.
Wouldn't have one myself of course - but i like spending weekends trying to get Linux running on obscure hardware.
