So, I've been using Macs for a little over a month now, and I have to say that unless Windows really steps up their game, I'm not going back to the PC as my primary computer. The Mac is just better. My experience in learning OS X, and transitioning from Windows has been extremely pleasant. I'm not a Microsoft hater, far from it, it's a Windows world, and as a result I have Microsoft Office installed on both Macs. Office is better than iWork (Apple's offering). I've even encountered a few websites that don't like the Mac OS, and that's frustrating, but it's a price I'm willing to pay for the ease of use I'm getting from the Macs. I've still got an older Windows laptop that I'm keeping around for things that absolutely need Windows.
My MacBook and my Mac Mini are networked, and it was the easiest set up I've ever done. I selected "Share" on both computers and within 20 seconds all of my wife's iTunes stuff appeared on my laptop iTunes. A lot of the stuff you can do with a Mac you can do with third party apps on PC's, but it's nice to have it built in. The iLife utilities really are all they've been made out to be. Web design, music creation, movies, DVD's, and photos are all handled with an intuitive interface that generates some damn impressive results.
My main complaint about the Mac would have to be the "DotMac" service. DotMac is a suite of online utilities that you can use to synch up information, store files online, and host web content. You also get a @mac.com email address with it. The service costs $99 a year, and it's really weak. When Google is giving away almost 3 gigs of storage for nothing, I should be getting at least that much for my $99. With DotMac I have a gig of storage to split between my email, my web content, and my online file storage. For free I could host photos on Flickr, post on Blogger, and store files on Gmail using Gmail Space. It just seems like a waste of money, and if it weren't for the seamless integration into the OS and the iLife utilities I wouldn't keep it.
Windows Vista is going to pretty much be OS X on a PC, and I feel like I'm already there. I can't wait to see what Mac comes up with for their next major OS release.
