Tablets, even expensive ones, are not really expensive
Compare a (wifi only) tablet to a mobile phone: the phone costs a zillion times more due to the monthly fees. A wifi tablet is a simple one-time purchase costing more than a good bottle of wine but perhaps a bit less than one good tire. You can drop the idiot fanboi approach and just buy one of each - thereby gaining access to multiple App Eco-systems (best thing ever!).
Apologies in advance to those that are forced to choose only one or the other and are thus trapped within a single eco-system. It must be awful.
