That's complete crap. Mac's aren't for everyone, but I can tell you that every single person that I've convinced to buy one since I made the switch in 2006 raves about them. I'm typing this on the first Mac I purchased, a $400 Mac mini with a G4 processor and 512 MB of RAM. I don't have any anti-virus or anti-spyware software installed and I've never had a single virus or a single piece of malware or spyware. I've never had a single piece of hardware fail, I've never had to reinstall the OS or any program on this system and I've only ever had to do a hard reboot twice in the entire time I've owned it. With the exception of a hardware failure I can not say any of the above about my shiny new Dell PC at work that I got in January of this year.
I've convinced 6 friends and family members to switch to Mac's over the years. I've received a total of 3 calls to help them with things since they got off the ground with a good understanding of how to use the Mac. In the last two weeks I've had to help 3 of my Windows using friends with things (one was hardware related and the other two were malware infections and they both did have name brand anti-virus / anti-malware software installed).
I can't rave about Mac's enough. The extra few hundred dollars you'll spend on a Mac is completely and totally worth it if you value your time at all. I used to be one of the biggest Apple hating flame throwers around. My buddy in high school had one and it was POS. Not anymore. It's worth every penny plus some. Get yourself a 6 month old Mac mini and try it for a while. You'll be happily shelling out over a $1,000 to get a better model within 6 months and 5 years down the road you'll still be using both.
Apple's are for people that are too busy getting actual work done to want to waste time updating AV software, reinstalling the OS, defragging their hard drive, re-installing screwed up software, removing malware, and installing hundred of OS updates.
And thanks to brilliant open source software like NeoOffice (an Aqua port of Open Office) that exists for the Mac, outside of the OS and the apps that came with it, I haven't spent a single additional penny on software. I spend all day at work fixing fubar'ed Windows PC's. The last thing I want to do when I come home is do the same thing.
And should I come up against some situation on the Mac that's too much for me to handle I can make an appoint at the Genuis Bar at the nearest Apple store and get help with it for free from a real live American citizen making a decent wage and not some dude pretending to be named "Phil" who I can barely understand located in a call center in India making $2 bucks a day. Again, worth every penny plus some.
