I have to admit, the cost did give me some pause. But the design and possible layout of these mittens won me over. I think the fullhand would be imminently practical (given how hard it would be to find a wristrest that fits that bend). However, the size of the fullhand does make it a little unwieldy on smaller desks. Decisions, decisions. I'd be inclined to go for aluminium given the impossibility of getting a replacement case for this board (I asked them on livechat about the alu case samples - they told me they don't have any on hand, but will get back to me as soon as they can. marvelous customer support, I must say.)
