Well,
my experience with WinMX is that it is far more stable than Morpheus.
Since this is the first beta, I wouldn't judge too hard based on it. But it sure will be exciting to put it through its paces. Right now there isn't much to download and try out the multi-sourcing, but that should get better in the coming days.
I feel all antsy already...
Stoepsel - hoping that WinMX puts an end to disappearing downloads
