Most of the world lives with dumb phones and don't dissolve into childish fits. How to explain that?
Most of the 3rd world lives with dumb phones that work well for the tasks they are designed to perform which are to make calls and send text messages. The device in question is not able to perform any of the above named tasks without running into problems. This would frustrate anyone no matter where they live
If the 'problems' are lag and failure to multitask (as listed) then they are only problems of patience, as I mentioned. This does not frustrate anyone; it frustrates folks who feel entitled to the best.
Except a 5 year old Symbian phone is capable of multitask without any issues.
Which matters only if you've ever owned one.
Asia, the market intended for Firefox OS, is one of the biggest ones with feature phones and Symbian devices.
Maybe because they have more people there? Most people, even there, own non-smart phones.
That's just it, though. If a "smartphone" offers a worse webbrowsing experience than a "dumb phone" with Opera Mobile that runs well on its resource-constrained host, why buy the smartphone?
