In my case I got fed up of replacing drive mechanisms after about the third one so I invested in one of these. It has the side benefits of much faster loading times and a much quieter console all round, too.

I won't deny that there is also a piracy aspect to it - I have a fairly large collection of boxed original Dreamcast games but there are a few on my GDEmu that couldn't be classed as "backups". The unreleased Half-Life beta is well worth checking out, for example.
