The pegasos is fun. And it's good for having fun.
But when you get one first step is to accept that
it's operating system (MorphOS) is closed source
and the few ppl responsible for the current version
spend only their free time for a future of it.
So it's uncertain when and if a new version comes.
I think you should only buy a peg if you like
what is available now.

I like what I have and would go for a peg again !
