"Was it really only a little over three years ago that the formerly fanciful notion of being able to run Windows apps within OS X without major limitations became reality? Today, archrivals Parallels Desktop and VMware Fusion continue to undergo aggressive upgrades aimed at making the virtualization of Windows on Macs even more powerful, seamless, and simple. And today, VMware is announcing that it's taking preorders for VMware Fusion 3, which will ship on October 27th."

In what regards do they suck? I find VMWare Workstation very useful for testing on Ubuntu 9.04 64-bit; I regularly run about 5-7 VM's at a time on a 4 core, 8GB RAM machine.
Disk access primarily, The rest is fine.
VMware Workstation on windows has about 3 to 4 times better disk access speeds than (an optimized) Linux. The VMware developers claim that it is because Linux does not allow detailed control over dirty page write back.
The best workaround on Linux is to run only one VM at the time, use a physically separate disk for the VMs and if possible a hardware raid controller with battery backed cache (like a perc 5i for example).
Another possibility for speed up is raw partitions, but these require special configuration and makes the VM difficult to move around.
Finally you got iSCSI disks, and it also improves performance somewhat.
However the workarounds above also improves performance for the windows system so standard Linux still lags.

On my MacBook Pro with 4GB, I run about 3 to 4. Also very useful.
