I had a G3 power Mac tower for quite a long time, i bought it from a business bankruptcy sale back in like 2003 or 2004, and while cool to say "I have a Mac", i was never really sold on OS9 (or any of the early builds of OSX). It spent more time sitting in our office being used as a media storage computer than anything else...seemed like such a shame too considering it was pretty pricey for back then.
I remember the day i saw the Macbooks and Macbook Pro's change over in 06/07...i was never sold on the Powerbooks, and had been a loyal Toshiba Satellite user for about 5 years at that time (why that is, i couldn't tell you, since ALL of them were pieces of junk). That summer (07) i bought the first generation iPhone, and was sold...i waited until that fall because the guy at the Apple store told me the computers were being refreshed, and in November i went and bought me and my wife regular Macbooks (she got a 2.0ghz model, i got the 2.2ghz model...i wanted the black case one but they were sold out and truth be told, outside the hard drive, there wasn't a $200 difference in abilities between it and the one i got).
It was all down hill from there...i built both of our macbooks up and hit a wall with RAM capabilities, so we sold those and bought Macbook Pro's in early 2009 (actually kept the older macbooks as they were great for being hooked up to the TV's in the living room and bedroom)...i bought a mac mini in 2009 as well and built it up to be our main media center hub, and it has proven to be an amazing trooper that handles all the movie, music and other downloads we throw at it.
And just recently, we sold off the older macbooks (it's amazing how their value holds if they are taken care of) and my macbook pro (her macbook pro was stolen around new years while we were having dinner, that sucked big time but she was able to use her old macbook as a good backup because that's basically all it was used for was a back up machine for important stuff she had)...went and got two 13" macbook pro i7's and have been completely happy with them thus far.
I personally can't even remember what it's like going to the store and buying a Windows based PC, but i do remember the feeling of necessity vs. the feeling of WANT every time i went and bought one of those Toshiba machines or the two Sony Vaio towers we had, no real satisfaction or happiness...just kind of what i had to do. Now, with every Apple computer we've purchased, its like sheer joy to open it up, fire it up and start using it. I dual boot Windows on my macbook because there are a few things i do that require software not available to mac yet (a couple for work, one for school)...but overall, it's been a match made in heaven, and i doubt i'd ever go back to a windows based PC (by my own choosing anyways). Mac OSX is my home, and when i go back to using Windows, even for a few minutes, i feel like im doing work, because its just sloppy in my opinion (and yes, im running Windows 7, which is apparently the most user friendly, lol)...Windows deff has some abilities that OSX has yet to master, but in all honesty, i prefer a clutter free working environment, and Windows to me feels like the worlds most cluttered desk, where yes...work can be done...but i hate every second of it.
I'm an Apple user for life now, and while i'd certainly humor checking out an updated Windows machine if it had some serious reworking and polish, i doubt i'd ever actually invest my money into one, because honestly, i've never had a long term good experience with ANY PC running Windows that i've ever owned (and i've owned several)...our Apples have been amazing, and i don't mind paying more money for that satisfaction AND peace of mind.
