I've heard really good things about the Ploopy Classic and the Ploopy Adept is going to be on my radar whenever it starts shipping (funnily enough this is article title is a welcome surprise because I misread the CAD pricing and thought the Adept was selling for $80 USD) -- but can anyone attest that these things actually work well for normal computer usage and are precise enough to use a full mouse replacement?
Is this something where I'm going to buy it and be immediately thrown off and will need to spend weeks learning how to reuse it? I love the idea of a stationary mouse that doesn't give me RSI that I can just plonk down on a desk or on top of a tilted display, and I love Ploopy's implementation of that idea, but I don't know if the reality is going to match the vision I have in my head.
