I bought an iTouch 2 years ago, is now completely outdated, and I'm £150 in apps out of pocket (never mind the cost of the damn thing) [though most of those I also used on my phone ] but anyhow, Apple have denied me the privilege of updating past iOS 4.3. Go for something android is my call...
Perhaps, but I think that will happen far less rapidly than with the iTouch/iPhone... the trouble is also, Apple do it explicitly to sell hardware, so "If you want the latest software, you need to buy the latest device".
Oh please, you're just making excuses. You are talking about comparing a sophisticated music player with a few other functions with smartphones; pocket PC's with cellular telephony. The demands on such things are much higher. Just exactly what do you think an upgrade to iOS5 would achieve on a Touch? Very little that would improve the underlying function of a Touch. It has no GPS, no cellular capability, only wifi.
Google have little or no interest in creating updates of their OS for older devices, there's nothing in it for them. Their customers are looking to sell the latest whizzy handset and encourage consumers to upgrade as often as possible. If you think Google are being all altruistic, unlike nasty Apple, then you're seriously deluded.
There are no specific music players running Android. There are a number of Pad devices running Android, but they are not designed to be used as music players.
Be honest, and admit that you didn't want a Touch in the first place, but couldn't spring for an iPhone, and now you're a bit fed up with its limitations you're just trying to justify a cheaper replacement that, gosh, just happens to work as a phone as well.
