I have been using my G4 PowerBook for a week as my main computer and I must say, I am thoroughly impressed by the speed of the machine, considering it is 8 years old. It is running 10.5.8 and has the maximum 1.25GB of RAM. How many more years do people think the PowerPC platform will be supported for/last for basic tasks? I use it to browse the internet, as well as Office 2008 and Logic 8 to record instruments and audio, although I edit my arrangements on my MacBook Pro where I can use effects etc. Many thanks.
