my technolust isn't necessarily waning, but I find that the older I get, the less I feel the need to keep my computer on the bleeding edge.
at my height, I was doing major upgrades every 3 months... now, the last major upgrade I did was over a year ago, to get my specs up to be able to play FFXI. and unless I happen to come into some money, my next major upgrade probably won't be until next fall (making it almost 2 years without a major upgrade)
... by major, I mean new mobo or cpu, an extra gig of ram, new high-end case, etc.
