Threads have been available in Linux for a looong time, PnP is not a new
feature either. HAL is being developped, yes, but I don't really see this as a
"must have" feature.

I don't think it's fair to say this. Everyone knows that Linux outperforms any
NT in most areas, and I wouldn't want to start enumerating all the features
that NT doesn't have compared to UNIX-like OSes.

lack of modularity?????? Oh no, please... try to get some facts before saying
such things. Speaking of compatibility, tell me just how many different
filesystem can be mounted on NT?
Of course I don't think that everything should be UNIX-like, I like the idea
that different solutions are available. I'm really looking forward to ditching
XP for ReactOS.
