I just upgraded to iEmulator 1.7.7 and wanted to let you guys know how it has been. For those of you that don't know, iEmulator is a PC emulator that runs on OS X. It does basically the same thing Virtual PC does, with some limitations. However, at around $24, I think its a great alternative to the higher priced M$ app. The release notes say that 1.7.7 adds a 6-11% performance increase (according to benchmarks). Upon loading it, I would have to say the increase is very noticeable, and seems more like a 15-18% boost, but that's just my perception. I don't know how it compares to the performance of Virtual PC. It seems to run about the speed a 1GHz Pentium PC would run. And thats on my 1.33 GHz G4. The other nice feature in the upgrade is that it allows the emulator to read the hardware CD/DVD drive, whereas before you had to make a Disk Image, which was pretty annoying. So that was a pretty big limitation taken care of with this update. I think the biggest improvement needs to be in sharing files between the two environments. This is where Virtual PC is probably more advanced, I've heard you can drag and drop from one environment to the other. Its possible to share files between the two environments with iEmulator, there is just a complicated setup process where you basically share your HD on your Mac over a network and the emulated PC reads the network volume. So just wanted to let you guys know. I use it mainly to look at the websites I design to make sure they are compatible with IE for Windows. It also helps me out to be able to load Windows when I'm trying to tell my mom or grandma how to do something on their PCs.
