just find one you like that has the features you need. I personally have had just about every major model there is including Dell and HP and never had a problem I did not cause. they all have lemons in addition to recalls and they all have great models.
I purchased a Mac Mini and decided I do not like OS, so I'm looking at desktops. I've been told that Dell is the least likely to have issues and others have said that HP is the best. I'd like to know how CNet or any experienced techies rate these two and why.
