Update...

Been a while since my last post so here goes...


iMac:
iMac has been back into Apple Store for the constantly running fan problem. Had a new fan fitted which failed to make any difference.
Eventually contacted Apple Support and, after another visit to the Apple Store with no fix, Apple have agreed to replace the G5 with a brand new Intel iMac. Thank the gods for Applecare...
As it was a straight like for like replacement I was offered the base model, a 20" 2.4GHz.
I decided to try for a paid upgrade to a 24" 3.06GHz and this has been accepted. So for the difference in price between the 20" and 24" I will hopefully be 'future proofing' my desktop Mac for the next few years.
The machine was becoming impossible to work on - the CPU fan was running at 4500rpm almost constantly. The ability to do any work was being affected by sitting 18-24" from the fan which was almost like sitting in front of a hair dryer. Even just using a browser would cause the fan to start speeding up. I even went back to Tiger to see if the extra load of Leopard was the cause but it still happened.

iPhone:
I finally gave in and bought a 16GB iPhone 3G in black - while the 3G cover is a bit sparse around where I live, if I travel 8-10 miles east, west or south I get into 3G-land.
One of the first things I did was apply InvisibleSHIELD to the back and Power Support Anti-Glare Film to the screen. The IS film was a bugger to apply and still has 'bubbled' areas around the corner cuts.
So far I am pretty happy with the device and wonder if the IS film will help prevent the rear case cracking that seems to be getting reported on various iPhone sites...
