I've just got a 10 inch android tablet off ebay for £99 with leather case and additional keyboard and GPS locator. I've downloaded a free office program, and a free file organiser and it now talks happily to a USB stick. It took a bit of working out as it doesn't work like a PC exactly. It will also take data cards so I reckon I could put songs on data cards - but I haven't done it yet. It has Wifi but is not set up for a broadband dongle (yet) I figured that wifi was likely to be enough for my needs.
