That's probably the goal to have brought Connetix VPC, but I doubt we will see signifiant upgrade to VPC for Mac. Microsoft will do a custom version of VPC for the XBox 360 (for it's hardware specific), it doesn't mean they will port the technology to VPC for Mac and I doubt they will do it, they cripple all they software for Mac, common Office nearly faster on VPC then it do in OSX directly; MSN doesn't have any worthy features, eat resource like hell and he's slow like a turtle with no leg; Windows Media Player for OSX anybody? doesn't even play all there own format in it.
If you're hoping to see a good version of VPC, you better learn programming and make it yourself, cause from Microsoft it can be a long wait to see something worth it. By the way, bring us a good version of iChat with real MSN support (no jabber, locked features) or any well do MSN supported appz with video and audio conference, so I can communicate with all the sheep from Windows world that use the default stuff. That's the only appz of Microsoft I still use. Please don't talk me about Mercury, it's bloat as hell. Fire? not bad but not really better then MSN (but support a lot of protocole, but I don't use them). aMSN not bad but not good. Let pass the other in developpement.
Windows on Mac, maybe Guest PC (was bluelabel) will become something, they make a good start let's see where they bring it. MacBochs, humm ok, let pass over even for geek who can set it up. QemuX (Qemu version os X) maybe a good hope, I haven't try it yet, anybody can comment on this one? iEmulator is base on Qemu.
And our best hope are.... DarWINE. Still under progress, but I believe they need a lot of help, I wish I was able to help them
But I believe I'm gona see a flying cow before Microsoft update VPC with decent features, not a new copyright and G5 or Tiger support, ok that's great but is it all that can be done since the time they brought it? they have the source code of windows, no? can't they make some more tweak? AHHhummm.
Back to the subject, it's a good thing that the XBox is backward compatible, all XBox owner will be happy with that.
