we seem to have had a lot of trouble with acers at work, weather it was a bad batch I dont know, we had alot of battery failures, and overheating issues.
HP seem to be good, and their support is great, good value for money, sony vaio, also good but are more expensive.
TBH, for home use, buy one that fits your use, I have a 6y/o avent running great, my home PC is 8y/o still does ok for most stuff (although im building a new machine at the mo)
