Nice! Can't wait for some performance numbers, will almost certainly purchase. On my A2000 with a Thylacine Poseidon was just too slow to even use a USB mouse. Fingers crossed that Jens' hardware performs better; I suspect it will!

Edit: just browsing the site. It looks like there's three different versions? The cheaper one listed for X-Surf 100 says it doesn't work with clockports, even though it has a clockport connector. The more expensive one says it works with clockports and also the X-Surf 100, is that correct? So even if you're purchasing one for the X-Surf 100, would it be better to purchase the clockport model if you think you might want to use it in an A1200 in the future, for example?
