Hi there! Welcome
You can use a mouse or tablet at your preference with any version of ArtRage, no need for a specific version for keyboard or tablet. The versions we have available are the OS X version, Windows version, and UMPC version ( if you're running an Ultramobile PC specifically ).
There's also a Wacom version, which is the same as the Full Edition ( it just has some Wacom badging but is the same in terms of functionality ) which is bundled with some Wacom tablets in Europe.
For what you're using, you'll want either the Starter Edition from www.artrage.com/artragedown.html for either OS X or Windows, or the Full Edition which can be purchased from www.artrage.com/artragepurchase.html
If you haven't used ArtRage before, I'd recommend grabbing the free Starter Edition from the link above and trying it out so you can get a feel for how it works. Hope that helps! If you have any further questions, feel free to post them on the forums or email me at firstname.lastname@example.org.
