I run Pro, too. I came from XP and knew that it was a feature I would want for possible compatibility issues.
And I am aware of the three features Pro offers over Home, the most valuable of which is the XP mode. The other two have to do with networking. Primarily these are tools for business environments. But offices have been mapping network drives for 15 years without Domain Join; the wizard makes it easier but it was never rocket science. The other is that IF you use W7 back-up you can put the back-up file(s) on a network drive. Many home users won't even use the built-in back-up utility; some won't back-up at all and many will use products from other vendors (many regulars including you I believe use different back-up software) and only a small percentage of what are left will need the info sent to a network.
I'm not saying Pro isn't good and I'm not saying it isn't the right product for you personally, or for me, or anyone that wants to play Networked MSHearts (which W7 will NOT run natively or in compatibility mode). I merely disagree with there being any "prestige" to owning it. I have never been one of the cool kids, I've always been a nerd, but I'm fine with who I am and with the version of OS I chose because it offers what I need it to do. I think a Camaro may help you get ladies who enjoy that type of thing but if you wear your blue W7 Professional box pinned to your shirt it will only get you stares and laughter, except maybe on Halloween.
Frankly I think you are cooler because you run Mint; Linux users were always the uber-geeks and super-nerds who could do anything from a command-line. I've never attempted to run Linux so you have conquered what for me is still an unknown.
For the users reading this, you should run what best suits your needs. If you need the ability to run the OS in more than one language, such as a family computer used by some Spanish-speaking relatives and some English-speaking, well then get Ultimate; it would be well worth the money for you.
I won't think less of you if you use Home Premium (sure if you have starter on anything but a netbook I will

... but even that how would I know unless you tell me???) A website can detect what version OS you are running but they care more about which browser and your email won't give it away so who's going to know?
