"I might actually get a tablet if it will run a full OS as well..."
I used to think this way, but I took a hard look at my computing needs, and 95% of it can be done with a tablet running Honeycomb (or with one of the apps already released in the market). Windows 7 is far too heavy to run efficiently on any tablet within reason (Asus has a tablet running windows 7, but it starts at $1000 with no keyboard or mouse, and probably has the same performance of a new android tablet once you factor in the weight of the OS).
My bets on the Asus Transformer... A tablet with a full keyboard, touchpad, 16 hour battery life!, usb ports to add any sized external hard drive, and the ability to VNC to another computer with a full OS for the time you actually need a full OS.
