Regardless of how frequently they are updated, they continue to work like a charm into old age. I have had my Powerbook G4 Titanium for 8 years, and I am running Leopard with no problems. I play WoW, do my design work with photoshop CS3, and compile code in XCode daily. I could sell it tomorrow for 400$ if I wanted to.
¬ Ever heard of someone still using an 8 year old PC laptop? LOL
¬ Can you run Vista [Leopard equivalent] on an 8 year old PC laptop? LOL
¬ Can you still sell an 8 year old PC laptop for more than 200$? LOL
So what if the next one is updated. Get over it and stop the gadget-desire for the latest and greatest. You’ve invested in something that loses value very slowly.
