Oh ive had some trouble with missing laptops. I live in the UK and bought from a german company Gericom back in September. They took AGES to get the laptop built, 9 weeks to be exact (all this time im without a computer - not too good for a software engineering graduate!) and then sent it using DHL.
It left germany, and as soon as it was scanned in their UK depot it went missing after being in the UK two hours!
Add to this i was going to the usa on holiday and wanted to take it with me! DHL game me a goodwill payment of 200 pounds (about 350 dollars?) so I went to the usa with no computer.
To cut a longer story short, Im looking to get a dell 8600 now.
I have had a lot of things shipped with UPS and never had any trouble. I am truly sorry to hear they have just "lost yours" as that is exactly what happened to me with DHL. But as others have said, really complain and you may get an extra lump sum for the pain and suffering, in which case max out the dell! I couldnt have bought the Dell 8600 im looking at without this mistake on DHL's part.
