I did pretty well on a 256 meg slice. I outgrew it after awhile, and I'm currently running 8 mongrels on a 512 slice, and I'm pretty much hitting the top.
RAM is by far the biggest bottleneck for me.
Overall, Slicehost is great. I just wish they'd include more RAM in their plans.
I have several slices.. putting nginx in front of apache and lowering down apache's processes has really helped me tighten up my memory needs (I use django).
