I’m using a Dell Venue Pro 11 tablet with their Mobile Keyboard.
Windows tablet and if you dock it to the keyboard it’s more like a netbook plus the Mobile Keyboard has an extra battery in it. So can use it for casual tablet style stuff, and then for doing accounts and stuff where touch is fiddly, just dock the keyboard (in fact I’ve even got Visual Studio on it for light dev work if I’m not near a desktop).
HDMI port to connect to displays, but it can also wireless project in Win 8.1 if your display or TV supports it.
There are different versions, one being a Bay Trail Atom based version, low power, flash memory, and the other is an iCore beast with an SSD drive. The latter is more battery hungry and not sure but think it has a fan in it too. I’ve got the Atom based one, and that’s perfect for what I do, and not particularly slow.
Like many flash memory tablets the storage space could be better, but everything is stored in “the cloud” these days.
