At the time I tried (2009), I was too young and afraid of messing up my Windows (I didn't even know if I was able to remove Windows and not loose the warranty), so I was finally did thanks to the marvelous Wubi installer. It let you try Ubuntu without messing around with partitions. Thanks to that, I was able to start learning Linux until I gained confidence and did a proper dual boot.
Now I only use Arch, even for work.
Been uing them for a long time. But it is really hard to find a good one under 40/50€. Normal mouses have a lot of the goodones in 30€.
