Dell are actually fairly reliable, however their cheaper ranges have 2 faults. First is that they cut corners to get so cheap (often on the HDD, RAM, motherboard and PSU) and second is that they produce so many more laptops than other companies that they naturally have a higher number of failures. You have to look at it as a percentage to get the full picture. Compaq on the other hand are only cheap but have no redeeming features.
It's like the BS about Acer being a "company to avoid" - they produce laptops nearly on the scale of Dell, except they push for a higher price point (with better specs). It's only natural that a higher number will fail, but in terms of percentage they're more reliable than HP and Apple even.
