OK after all I've said I decided to order a copy of Leopard, even though I'm gonna get a new Mac, it may not have Leopard on it if it's a 2nd via Ebay, but even if it is new and has the OS, I decided that I needed to get Leopard onto my Mac Mini. I've had so much info about the good stuff and the negative stuff seems to be a little geeky.
I also ordered a new keyborad as when I was at the MacExpo Live I tried one of them and liked it a lot, and at the moment I have my work Keyboard, my old PC keyboard and the Mac key board on my desk! What a mess that is..... Anyway grabbed a 20gbp discount code for John Lewis with Free Delivery I couldn't resist.
