The first Mac in my life was our first 'real' family computer: a Performa 630 back in '94. Back then the HDD was only 350MB or something tiny like that (by today's standards). In '98 or '99 we upped it to a PowerMac 7300. A whole gigabyte hard drive!
By the time the next Mac in the house came along, we had reached the point where we were using our own computers, so the Power Mac G4 MDD was primarily my dad's whilst I was stuck with a Compaq PoS to do my coursework.
Shortly after I started uni I got my first Mac that I actually owned: A Power Mac G4 MDD (dual 1.42GHz - beating my dad's dual 800MHz model

). A couple of years later I was spending less time in my parent's house and more round friends houses, so I bought a PowerBook G4 - the last of the PowerBooks (the MacBook Pro had just been released, but I wasn't about to jump to MacTel just yet).
In 2008 I bought the first unibody MacBook Pro that you see in my signature. A fantastic piece of kit.
Shortly after that, work were about to throw out an old PowerBook 1400c (c. 1996). I could't let that happen, so I took it home. It's still a better built machine than any of Dell's laptops that I've used.
I still have all of my Macs. My PowerMac is basically a music server playing music through AirTunes through the house, and the PowerBook, now a little beat up, still gets used from time to time for basic browsing. My dad still has all the old family Macs, right back to the Performa. I also have adopted my GF's old iBook now she has a MacBook (although she barely uses that now she has an iPad).
These are my Mac Memoirs.
