As always, people's "mileage" varies. I've never seen any evidence, on any
system at home or at work, where RD caused ANY instability. The only app
I'm aware of that ever had problems with RD was Photoshop, but that also had
problems w/ Apple's VM. And it's been fixed in recent versions. (Besides,
who in the world is going to be using Photoshop on most Duos, the 2300
excepted, of course.) Also, there's a body of objective tests out there,
done by the various Mac rags a while back, that shows RD's "slowdown" is
*maybe* 1%. That is, totally unnoticable. You'll lose way more time than
that futzing around in a smaller memory space. And you'll be slowed more
than that by Apple's VM, because Apple's goes to disk only. Oh yeah, and
since RD doesn't hit your HD except in extreme situations, you should have
better battery life. And we mustn't forget the many MB of disk you have to
devote to Apple's VM (24-32 MB may not seem like much, but it's 10% of the
HD space on most Duos!).
Just call me a very satisfied customer...
