Not sure if this is a troll, but I'll bite.
Actually, the best way to answer this is to explain why I switched from Windows to Mac about 6 months ago. I used to use Macs at work almost 20 years ago. I remember it being a big deal when we switched to System 7. I was very anti-Mac when I started that job, and in a gesture of grand irony, I was put in charge of taking care of all the office Macs. At that time we were running (I think) a Farallon network which used ordinarily telephone wire. Unusual back then. Anyway, I quickly became a convert when we started doing stuff like adding printers. You'd plug a printer into the network and suddenly all the machines could see it. That was it. Or once day for grins we popped a second video card into a IIcx to see what happened, and amazingly the OS recognized it and did exactly what you'd expect it to do.
But then I moved on a to a couple different software development jobs, and the dev tools always ran on PCs. Since we had PCs at work, when it was time for me to buy home computers, I always bought PCs. I started out on Windows 3.1, then 95, then 98, then XP. There are lots of things about Windows that I like, and lots of things that annoy me. But it's what I've been using for 15+ years now, and that's a lot of inertia. At home I have three XP boxes, a Linux box, and a Sony Vaio running XP. I have a ton of Windows software and the latest McAfee virus stuff.
Over the past year to 18 months, I've noticed XP getting less and less stable. It gets worse with every update Microsoft releases. Personally, I think this is not an accident, I think this is Microsoft's way of forcing us into another update cycle. They did the same thing to me with Windows 98 - they basically rendered it unusable, then stopped supporting it, and that's what forced me to XP, which forced me to buy a new machine when 6 months prior my 98 machine had been rock solid. I played around with a Vista machine, absolutely hated Vista, and when I saw this was the way their world was headed I decided okay, I've had enough of this ****, I'm outta here.
So I bought a Mac Mini to see how that world is, and I like it. I now use the Mac Mini exclusively for email, web surfing, and most document editing. I've switched all my contacts and calendars over to Address Book and iCal, and I like how well it's integrated into the rest of the system. Those little details are nice. And even though this just about the slowest and cheapest Mac you can get, it's generally pretty snappy. In XP, having an application freeze or die unexpectedly was almost a daily experience. On the Mac, I've found this to be extraordinarily rare. I still use the Windows machine for software development because that's where my tools are licensed.
There is a learning curve switching from Windows to Mac, but really it's not bad. There are things I don't like, and I'm still finding ways to work around them. For example, I don't care much for the Finder, so I bought something called PathFinder which is more to my liking. I hated OpenOffice, so I bought the MS Office suite off craigslist, though to be honest I still prefer Word and Excel on the PC to the Mac versions. But overall I'm happy with my decision and only wish I'd done it earlier. I love being able to drop down to the shell and work there, run shell scripts, etc. Probably in another year or so I'll outgrow the Mini and I'll kick down and get a full-blown Mac Pro setup of some sort.
I'm not going to try to talk you in to or out of buying a Mac. That's a decision only you can make. But these are the reasons I find the Mac to be "better" in case that's helpful.
