To be honest...
I know many would disagree - and feel free to. This is just my perspective.
My age has dumfounded me trying to get thumbnail of Big-TDI-Guy's picture of Leopard in here. Anyway, I agree, I should not have bought Leopard or then gone on to install 10.5.1 and 10.5.2 in the vein hope that things would get better - Tiger will be born again soon.
On another note regret having bought a house in 1988 at the peak of the property boom in the UK and then being lumbered with it until 2002 when I eventually managed to sell it for the price I paid for it! I had not lived in it since 1989 when my job moved. I sense a bit of deja vue.
