It has been less than ten months since we reviewed Parallels Desktop 5, a competent but buggy release from Parallels. Shipping paid updates with stability issues seems to be the company's modus operandi, so I was a little skeptical when I saw that a new version was already being released, since the last one had so many issues that needed ironing out. The feature list of Parallels Desktop 6 isn't what I'd call ambitious—the main focus of version 6 has been on the 64-bit host and increased speed, mostly for 3D and gaming. Gaming was already Parallels' forte, but I was curious to see if the new version would finally make playing modern games with complex shaders, high resolutions, and high-quality audio a reality. If it doesn't come through, and suffers from stability issues, this could be a disastrous release for Parallels. Read on for the verdict.

Interface changes

Most of the interface changes in Parallels Desktop 6 are subtle tweaks, but they make the application feel more polished overall. The new VM Library window has a slight transparency-with-blur effect over the background:

Resuming and suspending VMs overlays a similar charcoal gray and glass feel:

When you attach a USB device, a slick little window pops up:

This consistent feel makes the whole Parallels experience a little slicker and more in keeping with Apple's interface design. This is also helped by changes to...

That icon

I don't think many applications have received as much hate over an icon change as Parallels has. How bad is it? Well, I noticed this when searching for installation info for Parallels:

When your icon is so contentious that it's trumping "install" and "increase memory" for support questions, I think it's safe to say people don't like it. I was no fan either—just look at this thing:

The updated icon attempts to right some of the wrongs, while keeping the "parallel lines" motif:

The lines still feel lazily dropped on top of a decent stock icon, but it's an improvement, and the overlaid lines look okay on top of applications:

I'd still rather have the old icon back, but those pixels are behind us now.
