That's rare for HP, but you're absolutely right that it does happen, any company can have a bad product release. Toshiba who are traditionally considered one of the best laptop manufacturers have released a couple of absolute dogs over the years (in business grade gear). I'd still rate HP and Toshiba as the two best laptop brands thou :-)
Agree with this, also that any make can have a bad patch and even poor makes can sometimes produce good products. I would have liked my Acer notebook except for the trackpad issue. My complaint with them is threefold: First, I find it unforgiveable that they created this kind of problem in the first place by using an adhesive conductor when a soldered cable would have avoided the whole issue and cost so little extra, second, that they refused to consider that it was a real issue and kept fobbing people off by telling them to reinstall Windows or drivers or take it to a service center, third, that their 'service' was so poor. I won't buy another Acer because I can't trust them and the next problem may not be so easy to fix.
