Interesting comments - not sure fully justified. Head to head the poweredge servers we have had have p*ssed all over the HP (compaq) proliants that a consultant twisted my arm in installing (they were epically awful - every component, + motherboard, was replaced in both boxes in the first 12 months).
WRT to Laptops: we have run Dell, HP, Toshiba and Sony in various forms over past 10 years and all have had their moment but Dell have generally been the ones to last longest / easiest to fix. Batteries were Sony fault.
If you're running a rack nest then maybe enterprise-wise they come up short - I have no idea - but in the SME sector they do just fine.
