I finally succumbed to temptation and ordered a new iMac. I mostly blame Rikki who did nothing to stop me.
Most of my day-to-day work involves TextMate, Versions App and Safari. Hardly a power hungry suite of applications and until recently my white 1.83ghz white iMac has coped fairly well. The biggest problem I have is memory. The most my current Mac can take is 2GB and I often hit swap after a few hours of coding and testing.
The memory limit has become even more apparent while running VMWare for testing on IE8. This can consume around 700mb memory and makes switching between apps a lesson in patience.
The new Mac is the entry level 24″ with 4GB ram which should really help it zip along. It’s funny that I usually end up buying a new desktop machine just around the time when a new major release has been completed. I remember upgrading my old bondi-blue iMac to the iLamp when Ikonboard 3 completed.
