Leave it to laptop veteran Lenovo to make a tablet that's as comfortable with a pen or keyboard as it'll be with your fingers. The Android 3.1-based ThinkPad Tablet is a 10.1-inch slab that can work pretty much like most of today's Honeycomb tablets, but also allows you to add a $99 USB-based, full-sized keyboard and a digitizing stylus.
Like the HTC Flyer, the ThinkPad Tablet works with a digitizing pen that, unlike styluses used on traditional capacitive-screen-only tablets, can work on the screen even when your hand is resting on the touch display. It's also pressure-sensitive, which means you can vary the width of your drawing line by decreasing and increasing pressure on the screen, instead of selecting a different pen thickness. Even though there's a built-in slot ready and waiting for it, the pen doesn't ship with the $499 tablet; it adds $30 to the price.
