Firstly, stop buying tablets! Buy laptops instead!!!!!!!!
Anyway, I am not really sure it is worth it. Surface RT is quite limited, but £280 is a much better price, new iPads start from over £400, I still feel a £160 Nexus 7 is your best bet, or an XPERIA Tablet Z at the high end
If you are going to be silly and buy a tablet, it would be helpful if you bought a Win 8 one, so I can get these second screen apps on my touchscreen laptop
