Looking at the referrals to Mac vs. PC I found this post on why Linux (what version?!?!) is far superior to Windows 7.
I write this response just to show why what a Linux fan boy says is not to be trusted. I am not meaning that Linux is crappy or that it is not working, just that the reasons that the average Linux user will use to convince you are wrong, terribly wrong.
Power Shell vs. *nix shell: I don’t really think that shell is the real tool for an administrator, even if I have to admit that in some cases it is more powerful than a graphical tool. However this is not the point. Power shell is a object-oriented shell and this is enough to declare it the winner in the shell’s battle. I am sorry if you like do black magic to deal with strings but a character based shell is old, nothing else.
Windows setup vs. Linux package manager: the idea of the package manager is surely cleaner but when did you saw a Windows user become mad because of some wrong dependencies? In Windows setups takes care to provide the required things to do the job, so there is no real advantage using a package manager. And all the application you mentioned are available also on Windows without a very little effort. Can you say the same about professional applications?
Crash on a virtual machine: wow that’s cool. A crash of a beta operating system on a virtual machine (that in the past made mess with every OS had to run). It is definitely a reason to install Linux.
The aquarium: I am still thinking what is its use. Or is it simply useless? And My eyes saw both Vista and Seven run on a exec, is it too powerful?
WGA: it is a commercial product, don’t you want to be a pirate, right? If you don’t want to pay get free software, but not cry if WGA stops you using something you pirated.
UAC: are you running as root on you Linux-box or are you using something like su or sudo?
The register: you said you are cleaning your register, isn’t that doing more harm than the good things you would get?
