Some pages use Active X, which only works for Windows. Usually they are web-based programs... I've seen a few online web-site builders use the active X controls, which prevents mac and linux users from using that service.
Yahoo Video Launch also restrics OS X users from viewing their Music videos (but apprently it works in OS 9)
With VPC you can install Windows. It is just like having a PC, but on your Mac. Since it uses emulation, however, you will notice that it's a bit slower than OS X.
The good thing is that you can do almost everything with VPC, except for 3D gaming because it would be too slow to run. 2D games usually work fine.
There are several things you should know about VPC:
- You need lots of RAM. RAM is very important for VPC performance. Have at least 500mb or more RAM, I think 1g of RAM is recomended for VPC.
- The faster your processor, the faster VPC is. VPC will always be slower than OS X because of the emulation, but I hear that people with fast G5 processors find that VPC is workable, and the speed isn't so bothersome.
- Windows 2000 runs faster in VPC than Windows XP. XP uses more resources, thus it will be a bit slower.
- Get Tiger. There is a networking problem that VPC and has with Tiger, but if you don't need the networking right away, Tiger (for me at least) seems to make VPC a little faster... actually Tiger has made my entire computer much faster.
I have VPC 6 and I run it on my Powerbook G4 @ 1Ghz. I have both XP and Windows 2000, but I always run 2000 because it works much faster than XP.
Windows is slow, but it is still workable. My speeds are like a Pentium 500 Mhz...
I once tried Windows 98, which worked very well and was just as speedy as a normal Intel computer, but for some reason I couldn't get updates for, so I deleted it.
Once you install Windows, VPC will run it as if it's on an Intel machine. You can use Windows-only websites and use Windows-only program.
I usually don't have to use VPC often, because it's coming to a point when you can get the same stuff on OS X, and many websites are using OS X friendly websites and web applications.
But there are times I use Windows to test websites that I build, or access a web application that is for Windows only.
You can even run Windows Update to update your copy of Windows within Virtual PC -- and you may have to for the web-application.
Good luck,
