@Frank Bough - Re: made me laugh
It depends what version you were on.
My other half was running Leopard. We wanted an install CD to install a completely fresh OSX Lion onto a new drive (Leopard was grinding and acting very slugging - especially for a twin xeon machine with 14gig of ram!). We visited the crApple store and were told we could get a USB stick for £55... We had to pay for the update to Snow Leopard and then the next step to Lion or something like that.
It sounded like a load of bollox to be honest and I wished we'd said we were on Snow Leopard but didn't have an internet connection instead. As did the explanation from one of the geniuses about which graphics card was supported was down to the motherboard she had, not the drivers built into the OS when I was asking if an ATI HD 5750 was supported.
