VMware Fusion is an essential app for web developers! I can have Ubuntu, WinXP and now Windows 7 all installed on my Macbook running simultaneously. Only thing is I was compelled to buy a 7200rpm drive and 4GB of RAM to get the most out of this.. and it worked!

Version 3 is amazing, the developers have been hard at work and it's paid off.

It works like advertised, you just need good amount of RAM to use it since another OS is running. Minimum 1GB, Recommended 2GB (depending of how many apps open).

This app is cpu intensive, so I avoid using it in laptops when they are not plugged.

Use Vmware Fusion ONLY when you have some app you can't find in OSX.

For Games: Use BootCamp. It's faster since it's native and you have all the computer RAM available. I even use a stripped down version of XP for it.

I too have licences for both Parallels v.2 and VMware Fusion but prefer VMware. I didn't upgrade Parallels to V.3 because I found Fusion to be faster in loading programs.

I like Fusion a lot. But its the only app I have installed right now that has the propensity to take down my ENTIRE f*$Ying computer. Like basically lock up the entire machine. Happens regularly, but not frequent enough where I dont take a gamble booting it up every once in a while. Sure pisses me off though.

I have no idea if this is Apples fault or Fusion. Isn't OSX supposed to protect computers from rogue apps? Anyways, I'd recommend againt having anything valuable open when launching Fusion.

When its working (95% of the time), it works awsome and the usability is top notch.

I have licenses for both VMware and Parallels, and compare them head to head with each major release.

Other than a period after VMware 1.0 final was released and Parallels 3 was in beta, Parallels has always been faster to resume and restore, and has a much more polished user experience.

I tried the recent VMware 2.0 beta, and other than the new printer setup tool, it doesn't surpass Parallels in any way I can find. Some comments here about how Vista runs better on VMware, but can't say; Vista is too painful on either product IMHO.

So once again, I'm sticking with Parallels for now. Nice to see the two companies push each other, though!

Faster then the "other" virtualization solution for Mac. Unity is a ver nice way to integrate both world

Unstable waste of money. I really wanted this to work, but it didn't.

Not perfect, but I am happy with Fusion. An occasional lock-up (requiring a reboot as Force Quit does not work) and failure to release external USB drives back to OS X are the many problems. However, those are rare. Unity is simply superb. For those of us who, for whatever reason need to keep one foot in the Windoze world or who want/need same computer access to other flavors of UNIX, it is hard to beat.

I love this app! Set-up is straightforward and easy, and Unity rocks.

Fusion works flawlessly. Booted up my Boot Camp with no troubles (Parallels didnt work and the error message pointed to a broken link).

The UI is amazingly simple. I've been running my image in the background for the last couple days with no noticable performance problems at all on my mac apps (Macbook Pro). The Windows apps seem to run native speed.

Highly recommended
