Just thought I should post this up here I bought a Rev A 1.8 SSD from Viking Direct a week or so ago , I think I got the tip from here , so thanks for that ! But when tried to take up the ilife 09 upgrade offer , I was told my Serial is invalid I went into the online warranty checker , and again , there was no record of the serial - I assumed there had been a problem with my registration , so I went in and manually registered the Air via my Apple account .... I then went back into the Warranty checker , and it is showing my warranty as due to expire on 16th August 2009 !! meaning my warranty would be 6 months or so short ! OK so this is not the end of the world , there is an option to amend the details , which required me to fax my receipt to Apple , which I have now done , so all is well, But I can't help wondering what would have happened in 9 months time , if I'd had a fault , and in the meantime mislaid the receipt ? (my previous experience of Apple warranty was that the receipt was not even relevant, so I wouldn't have been overly cautious about looking after it !) On the whole , it is better rectified NOW than 9 months down the line when you have a problem , or find that you can't apply your AppleCare Just thought I should mention it , if you bought an old MBA from Viking , best check your warranty.
