This poll has really surprised me!! Absolutely flabbergasted, to be frank.
I never plat games on my mobile, not have bought any recreational software, but I do purchase my email client and a few others
I need my mobile device for everything, Finding the time and platform of the train I need in the morning and half way through a days work to get to another client site, hailing a taxi, scanning wifi networks for strength and channel consumption, scanning networks for open shares, accessing my email accounts and accessing various other things.
I stopped using any apps with adverts in them 3-4 years ago due to power drain and now run cyanogen with suser for data leakage, but my primary apps are still paid for, if if I don't have them loaded on every device.
If the people on /. don't see the worth of buying decent mobile apps - what's the point of them other than to advertise and hijack the masses?
