I've got a Sun Blade 1500 at home (one of the old red ones). Works great.
Apart from suspend/resume, that is.
I have no idea why, but both suspend and resume take an absurd amount of time. The suspend isn't too bad (slower than it should be), but resume is in the 5-10 minute range. To use an Americanism, this sucks.
(It's doubly odd because I've tried this on a Blade 150, and that's much, much quicker.)
