A friend of mine just emailed 3 of her friends saying:

"I just bought a new BlackBerry, it requires Outlook, how do I get it on my computer with Vista"

For her it turned into a 5 hour process to install an email client built by the same company. I would say this has a great deal to do with the usability of the underlying OS.

on Mac, a reasonably nice email client comes with the OS.

in most Linux distributions, a reasonably nice [insert arbitrary commonly used application] comes with the OS

why is that a reply to me?

umm, i gave a reason that email setup would be relevant to os (i.e., in a vista criticism). i did not say "omg mac is so much better than linux".

It wasn't clear whether you were criticizing Vista or responding to my claim that the goodness of default email clients was irrelevant to the evaluation of the OS.

These OS war threads are always overheated and people basically read what they want to read into your comments. Sorry for misunderstanding. I'm pretty done with this.

edit: I will say, though, the post re:linux also could be understood to point out the weakness of your argument in general, and not so much to claim that linux is better than both OS's.
