I'm typing this on my Windows 8 tablet, an Asus ME400. It's a full Windows 8 device with the latest Intel Atom dual-core 4-thread processor. It cost the same as the cheapest full iPad. Until recently I was using an iPad 2 but I gave that to my good lady.
The experience is a real mixed bag. This is the first time I've tried to type anything significant on it, and I am really missing the autocorrect. On the other hand I'm running full desktop Firefox just the way I'm used to it, and everything works fine with touch. It does feel much more like a real computer. Anything I want to do is a case of installing software I already have, which is lucky because there seems to be basically nothing interesting on the app store.
Using it as purely a touch device is somewhat unfulfilling. Web browsing and reading email are alright, and some of the bundled games are neat, but that's about it. On the other hand, if I reach into my bag and pull out my bluetooth mouse I have a PC. I can install any game that doesnt require the keyboard. Master of Orion 2, Starcraft, Heroes of Might and Magic 5. Heck, if I find the USB adaptor I need to plug devices into this thing I can use a 360 controller, or mouse and full 102 key keyboard 😛
But yes, it is basically a netbook built entirely into the lid of a netbook, costing twice the price of a netbook. The whole experience is nothing like as polished as the iPad, but its a proper PC. Touch is a lot nicer than a laptop trackpad.
