Although Parallels Desktop 7 promises to run graphics 45 percent faster than Version 6, I saw a mere 8 percent improvement in 2D rendering, based on the PassMark benchmarks. I did get a 44 percent boost for 3D graphics, so gamers and simulators should see a notable improvement. But note that Parallels Desktop does not support DirectX 10, so some video-oriented games and applications won't run.
That's not bad, but keep in mind such synthetic benchmarks tend to overstate what you'd get in real-world performance. For most users, I don't think it justifies an upgrade. Parallels 7 vs. Version 6 can run on Lion as well, but it does not support Lion's new gestures or Mission Control. Of course, virtual desktop clients for running Mac OS X on iOS are easy to find, and there are good free ones, so the main value of Parallels' enhanced iOS app is the unified virtual desktop.
If you already have Parallels Desktop 8 or 9 follow these steps to upgrade to Parallels Desktop During installation, the previous version of Parallels Desktop is automatically removed from your computer. If you were using a trial version of Parallels Desktop or you purchased a previous version but haven't installed it on your computer, you will also be prompted to enter a full or upgrade key for that version. Note: To upgrade from Parallels Desktop 2, 3, 4, 5, 6 or 7 you must purchase Parallels Desktop 10 at full retail price.

Of course, virtual desktop clients for running Mac OS X on iOS are easy to find, and there are good free ones, so the main value of Parallels' enhanced iOS app is the unified virtual desktop. Plus, the iOS app works with both Parallels Desktop 6 and 7, so you don't need an upgrade to Parallels Desktop 7 to take advantage of it.
What might entice you to upgrade to Version 7 is Parallels Desktop's new ability to create Mac OS X Lion VMs, with which you can run virtual Mac instances on your Mac, such as for beta testing or configuration testing. If you're a savvy Mac user, you can get past these issues.
The installer file is deleted by default once you install Mac OS X Lion, but there are ways to prevent that, as well as to access the hidden copy on your Mac.
