I am now a big fan of Apple computers. I used to be into PC's but genius that is Apple (though many will beg to differ) could take me forever to write up - and I probably wouldn't even cover all the bases. Don't get me wrong, I'm no computer wimp - I myself love different distros of Linux and I was a super XP fan, I still remember computers that booted up from a floppy and where a 10 MB hard drive was the size of two firehouse bricks. What turned me was my iPhone 3GS, the first Apple product I've ever owned. After that, my friend showed me his MacBook Pro with the large touch pad - I have never used anything as innovative in all my 20 years of computer experience. After that, I bought myself a MacBook in 2009, it's the white one with the large touch pad and no buttons, the touch pad itself is a button, just like the aluminum version.
Well, I can honestly say, my next power house of a computer will probably be the Mac Pro desktop. It's not just the hardware, it's the interface and the fact that a lot of programs written for OSX are written to optimize functionality of the hardware architecture.
With all that said: I post mostly on my MacBook or iPhone.
