This little handheld computer from Sony does it all. One seen in the image is the latest rev from Vaio group, the UX390, 32G flash based memory, 4.5" touchscreen, state of the art processor, slide up screen exposing a backlit keyboard; Wi-fi, Bluetooth caps, and pretty much everything a high-end laptop can also offer. The benchmark of handheld computing in this day and age with no challengers in sight. Will set you back about two grands which is essentially a steal :)
