Magic Mouse far too slow
I was very excited to try out my new Magic Mouse - It's certainly a design classic and a thing of beauty. BUT, and as with other posts here, as soon as I've installed the update for Snow Leopard I too found the fastest tracking setting far too slow.
I use a Macbook Pro 15" - but attached to it is a 23" Apple Cinema Display so tracking across the two screens was unbearable at the highest setting - having to move my mouse across the desk / lift it up and move it further to get to the other side.
This was one of my gripes with the old Mighty Mouse, that and it's not too smooth tracking at slow speeds (I often had to click somewhere near by and use the cursor to get to the right place in the middle of a word!), so I ended up with a super-fast Logitech G7 which was perfect (even without a proper Logitech dirver support for it for Mac), smooth accurate and fast. I was hoping Apple had brought the game to the table with the Magic Mouse - but not quite yet!
Having read this thread I've installed Mouse Zoom, which has certainly improved things (thought the acceleration / momentum doesn't quite feel right, too slow when moved slow), and will keep my eye on USB Overdrive for it's update.
Come on Apple - get your Act together and please provide a software update that makes using the Magic Mouse a pleasure for everyone, as it should be. There should be no need for third-party software, and I know a whole bunch of new non-techy Mac users (and even ones I've nearly persuaded to switch) that would simply be very frustrated with this, and not even think to look for a third-party solution for such an item.
