No one ever gets tired of this topic eh?
Use the right tool for the right job, every OS has its place and purpose and I use all of them on a daily basis.
It's obvious the target audience for Macs are typically trendy non-computer savvy people who'd never utilize OSX to its potential anyway and simply purchase it for a fashion statement.. that's fine, that shouldn't cloud judgement for the rest of the world who actually use the products.
Case in point, some poster mentioned connecting an old printer. Can you break into a BSD shell environment and set up not only the printer, but also a useable print server in 5 minutes or less in Windows? Nope. Does Windows have more support natively for devices? Yep. These aren't 'average user' scenarios but that's hardly the point here and infact the counterpoint to that age old userbase argument.
I'll say it again and again, use the right tool for the right job!
