Owned nothing but Window's based desktops and laptops up to 2005...I remember every time we went to buy a new one when the other one would conk out that it was never an experience of wanting the computer, but more needing it, and trying to find one that fit the most needs and felt like it was built the best. Had 3 Toshiba Satellite notebooks in a 5 year span, and they were truly awful (one of them being comparable in price to the Apple laptops at the time).
My sister, who was majoring in animation and graphic arts at the time, came over to my mom's place with her shiny new Macbook, and she let me mess with it for an hour or so and I was instantly hooked. I loved the primitive OS X variant, I loved the fit and finish, and mostly, the things I needed to do on a computer were must simpler tasks.
I went and bought one the next week...and never looked back. I had an iPod at that point, but never really considered Apple's computers because of where they entered the market on price. The apple store guy wasn't pushy, and left me with a thought when I was ready to leave and think about the decision..."You've spent "x" amount on Toshiba laptops in the last 3 years, and were never happy...what if you spent that on one device and it served you beyond your expectations for the same amount of time?"
Sales tactic? Absolutely. But you know what, it was true. Right now I'm typing this on a 2012 MBP customized to the gills and it functions absolutely flawlessly. I tend to clamor over new Apple products each year when they come out, but in terms of laptops, even after owning a retina model, I still go back to this one, because it is perfect for me...almost 3 years later. In a world of short lived technology, this thing is a dinosaur, but motors around like a damn thoroughbred.
The iPhone did the exact same thing for me...breaking me free of my former BB and Palm chains. Never looked back.
