VMware Fusion

Could of gone for parallels, but VMware is what i use on the other two platfoms, i did feel a bit down that i bought the version i have prior to the latest version, but hey, this is the IT world we live in, and it does what it says on the tin.

Needs lots of ram to get the most out of.

Got VMWARE fusion 3 running smoothly with a new copy of windows 7 64bit. Need to use Windows to access my work's intranet and server from home, otherwise wouldn't have purchased.
Works really well and has great integration with Mac Snow Leopard.

Favourite virtual machine application out there...
In combination with Snow Leopard and the newest version (VMware Fusion 3), it's quite impressive in terms of performance!

I'm working on a MacBook Pro with 2GB of RAM, and it runs quite smooth (using Visual Studio 2008, SQL Management Studio, ...)

Windows 7 support is great. No problems here, smooth interface.

i use too much ...just for work

Simply the best virtual machine application available.

A must-have for any user of OSX, taking into account its poor software compatibility. If it weren't for VMWare Fusion, I wouldn't be able to use OSX at all. Far too dependent on Windows applications. Unity mode is a very nice touch, allowing the user to run their Windows applications on their OSX desktops.

Stable, powerful and accurate virtualization with good interface (which is much more comfortable than VMWare interface on Windows and Linux).

so helpfull for mac user that need develop program in windows

Windows 7 RTM works like a charm. No issues so far.

Works well on OS X.

Works great with OS X.

Use it to run Windows XP installed in Bootcamp for work. Quite stable, but often slow for HD access (I have a 5400rpm laptop drive) compared to a "pure" VM. Don't like Unity.

Guys, what about parallels? I mean, which one is better in your opinion?
