I have been doing a lot at work lately with an HP Stream 7, which is a teeny tablet running for-real Windows 8, except even more real since the tablet only has 1GB RAM it ships with a "crippleware" 32-bit version of Windows 8.1, which being 32-bit will run all that software that won't run under Windows 8 because it's 64-bit.
Only problem is that the only I/O is the micro USB power connector. You can use USB peripherals with it with an OTG cable but that gets awkward and you really need a bluetooth keyboard and mouse for practical work. And reading glasses of course, but that's a given.
But there's a new player! Office Depot has on sale a similar tablet by "ICraig" which is a bit bigger at 8.95 inch screen, has the same 32-bit Win 8, and the same RAM and flash (the literature says 16 GB but the OS says its 32 GB). And unlike the Stream 7 it has a separate USB charging port, full-size USB, mini HDMI, analog headphone, and externally accessible microSD jack. And it comes with a docking keyboard folio/stand, so you only need to add a normal USB mouse to set it up like a laptop.
In a pinch you can also use the charging connector for another USB device with an OTG cable. Battery life seems to be comparable to the Stream at around 4 hours and of course you can use it like a tablet with the touchscreen. Wifi, bluetooth, fore and aft cameras on board of course. And it's on sale for $100 right now (normally $150). It's the best package I've seen yet for something really cheap and portable that can, oh for example, program a Propeller or Basic Stamp. Hey Erco, is there an Office Depot near you?
