The Volito2 is Wacom's entry-level tablet device, and at about $67, it could be worth it to have text input, photo editing and the ability to add digital signatures to your documents (which can be priceless). It's nicely designed even though it has a smallish active area. Other features include a USB 2.0 port and a battery-free pen but remember, it does need to be connected to your computer or laptop to work. Comes with ArtRage Wacom Edition painting software from Ambient Design, created just for the Volito2.
