I think I was maybe in 8th grade... I went over to a friends house to stay the night, and he was playing around on his iBook G3 which was super new at the time. It just looked like the absolute coolest computer I'd ever seen, but what really sold me on it was not just the aesthetics but when he opened textedit, he typed something and then he used the 'text-to-speech' function and it blew my mind, it was infinitely better than what windows at out at the time. I knew that I HAD to have one of those computers, so I nagged my parents forever and ever and actually ended up getting a mac for christmas that year. 🙂
I went from using a Compaq Presario with like 233 mhz, 32 mb ram, and a 4gb HD to a Titanium Powerbook 1.0ghz, 512 mb ram, and 80 gb HD. It was amazing! I still have it and poke around on it sometimes.
