Even better news for Mac OS X/WIN XP

As reported on MacRumors (click link on previous post), Parallels has just released its "Windows Virtualization" software application (Beta release) for Mac OS X - Parallels Workstation 2.1 Beta. This is different, and in my opinion, BETTER, than BootCamp. Pretty much similar to Connectix/MS's VirtualPC, you can run Windows UNDER OS X, i.e. having 2 systems ON @ the same time (Boot Camp allows u to "boot" 1 system at a time; to boot the other, u must "restart" your system). Despite the fact that both BC and PW2.1B can transfer files from 1 system to another with ease (BC requires u to install WIN using FAT32), only PW2.1B allows u to RUN APPLICATIONS on both system concurrently! The Beta is free, but unknown for the final ver., and most likely it's not, since both Windows and Linux pkg (final) is priced @ $49.99.

I do have 2 concerns:
VPC under OS X has been VERY VERY VERY lousy in terms of performance, even if u r using G5 Quad-Dual (from what I've read). By VVV lousy I mean it's no where close to native WIN performance, as some games (that are graphic heavy) won't run on VPC (and trust me, it isn't a video card problem). I use a G4 500MHz Dual right now (no $ to buy computer), and guess how frustrated I've been when using VPC (esp. when VPC doesn't really utilize the "dual" processors' power). I dunno if the PW2.1B will be as fast as (or even very close to) the speed and performance BC can do.
Now that Mac computers can run WIN, what's the use of OS X? I know it's a great system, and ~5% of the computer user population knows that too! Again, ~5%. Software companies will sure spend a whole lot of $$$ to develop their software apps to the Mac community when it's free to say "boot your Mac into WIN mode." Most importantly, other than the US, only a very insignificant portion of the world uses OS X! With most programmers and software companies moving to Asia (China & India specifically), which are both WIN's heavy (~100%) countries, how many companies will believe that spending their big $$$ to recruit Mac SW developers (engineers + programmers) just for the sake of the 5%. Mac users will argue to the death of this point, but remember, it's NOT the engineers/programmers that RUN the company (and making final decision); it's the business personnel (business and marketing analysts). If they believe that it's not fruitful to stay in the Mac business, which, when u seriously think about it - a very logical assumption - the business branch will just halt the Mac side development! (Excellent examples can be seen in the US airlines and auto industry). If most SW don't run on OS X, then who or what will cause OS X to stay (or why will Apple keep on releasing future updates for OS X instead of concentrating on its money making business, a.k.a. iPod)?
