Now that I'm used to it it works like... magic. It's precision is good enough for me and the swipes are very easy. I love it now, so it's just a question of giving it a fair chance.
You see, you can get used to living in an Igloo too. Settling with something thats 'good enough' for you is not a solution. This kind of things allow big companies like Apple to get away with things that you would be furious about if it were any other company. Like Logitech.
Not being able to change or turn off acceleration alone is annoying enough. Then there is this ridiculous non-ergonomic design. Its a wrist killer. Your muscles are constantly tense while using MM. A mouse with swipe features could be improved SO MUCH with a couple of buttons and a nice shape! Just imagine what the MM could be if Apple weren't so tight-arsed about design.
Apple's motto is Form Over Function. And most people are just happy to live with it because its Apple. Wake up people! Learn to complain about things that are bad. Only way to make big companies to improve things.
