OK, now I'm no OAP with a typewriter! However, I do still have the lovely Mac OS X 10.3.9...I never really thought the upgrade to Tiger was worth £89...but since there is the new OS coming out, do you think I should wait until it comes out and go to eBay and buy Tiger or Leapard-remember that I don't think Leapord has that many good and amazing new features, arguably, compared with the release of Tiger, or Panther for that matter. Money is a problem so obviously Tiger will be cheaper, and I have an iMac G5 512 MB RAM-nothing special Rev. A as well....so what you think, Leapord or Tiger, taking into account the conditions? Thanks, Tom.
