Android tablets, however, are another story...
Not all. I've got an Advent Vega, with a Modaco rom. It's PC architecture, so it runs very quickly (for a 1Ghz processor, I believe), and keeping things on 2.2 it's also nice and stable.
TV catch up sites like iPlayer (the web version, not the app), 4OD and Demand5 work perfectly, and full HD playback on a 10" screen is a joy. Angry Birds or stupid zombies are way too much fun.
The lack of 3G doesn't bother me, because my Galaxy S has WiFi tethering built in, so I just connect to it as a hotspot. I took it round to a friend's house a few months ago - James is an iFan - and we did a side by side comparison with his iPad. I concede that the viewing angles on the iPad screen are better, but that's it; there was nothing the much hyped Apple tablet could do that I could not on my 100 pound device.
My phone, however, is still in perfect condition. I've seen some pretty battered iPhones as well...
