All this talk about the great deal the refurb's are...I have to toss my experience in the ring.
The 24" Extreme ( 2.4Gh, 2Gb ram, 500Gb ) arrived and I had it up an running in 10 minutes. Talk about excited. By supper time I had all my apps installed ( Office '08 for Mac, LR, CS3, AP2, etc, etc ). Came back after a quick dinner and found I couldn't quit Safari, had to do a hard shutdown, reboot. Again, again, again.
Called Tech Support, on the phone for over an hour. Tech said I had to do a complete re-install of the OS. Got up in the morning after a fitful night and started the process...By 10:00 finished the install and guess what....same issue. Called Tech and they said send it back and connected me to Customer Support. They agreed to refund my credit card as I decided to go the 'new' route from the local Apple Store as soon as my card was credited.
A shipping return label for UPS arrived in the mail the next day and I dropped it at the UPS Store the same day.
18 days later I received a credit note for 124.28 in the mail. I called to question the amount ( the refurb 24" was 2280.00 ) and they said that due to a 'miss-communication' my 'new refurb' was on its way to me. It arrived the next day and I had to ship that back as well.
Its been a month and I am still out over 2,000.00, 12 hrs of time, 25.00 of gas, and no iMac. I have since heard at least 4 other stories similar in context from co-workers.
I has mistakenly thought a refurb would have been given a more through inspection than a new unit. Wrong.
