I managed to go for about a year with a company loaned Black MacBook Core 2. (I was working for an Apple reseller). Previously, savings, then went savings went, a little bit of savings from government unemployment payments. Now, savings again!
There was a period of financial mismanagement when I was blowing way too much money on Apple stuff ... maxing out my credit card. That was bad, that was in 2003-2004. In the past four years as I mentioned I've used instead savings, or, luckily, working for an Apple reseller where sometimes I get to set up new demo Macs which feeds the craving just a little.
I have enough put away for 0.5 of a Mac Mini ... excluding the resale value of my MacBook Core(1) "Yonah" 2ghz.
Hopefully through this year I will be able to save a bit more for a Mac Mini / MacBook Alu/ iMac 20" which I can afford from savings and trading in / selling 2nd hand my MacBook.
My white MacBook Core(1) is doing alright, 2GB RAM and a 7200rpm drive. Surprisingly adequate. Though the 3 year Applecare runs out in May, so after it runs out I am kind of hoping something goes wrong so I can justify a new Mac
I just have some cravings for gaming, I want to set up a dual 9800 GT in SLI -- a gaming PC. But to deal with Vista 64bit, though interesting, and then installing/buying games, then lugging around a heavy, noisy PC box... The Xbox360 is looking attractive although it has its own negative qualities...!
