As far as the cost is concerned, about £20 for the upgrade might be OK. However, if it costs > £1,000 because it needs a new iMac that is rather different - especially if we are expected (although not going to happen) to buy a new iPad next month despite having a perfectly good iPad1.

Not sure if my iMac will run ML as I can't remember exactly which one it is and at work at present. Not sure if any of the App changes are worth it really - Notes would be handy if synced with the iPad and a proper ToDo list outside iCal, although I have both of those using Third Party Apps.

To be honest, I find Lion to be better than SL was - for things like EVE Online and maybe a few other Games. For more basic Apps, no real difference.

Will probably wait and see
