I'm known at my job and with friends of being a Mac fan, which is true. It wasn't always like that however. I've spent the majority of my IT career behind a keyboard of a PC (well, and a Linux machine when I was a Redhat Server Administrator) ;-) Customers and friends often ask why I use a Mac, and I thought that this experience of a blogger who works for a site called Tuaw summed it up nicely. Just like he mentions- Macs are not perfect- but even when things go wrong, the overall experience has been way less frustrating than experiences that I've had with a PC.
And people wonder why Mac's are gaining marketshare, not only for the consumer, but in the enterprise as well.. ;-)
