I've had a bad history with Dell desktops, so I tended to stay away from them overall. They could be better now, though.
I have a little Acer 11.5" notebook, and I'm lovin' it. Build quality and components are great.
Although, I have an issue with losing the rubber feet on ALL of my laptops, be it HP, Acer, or Toshiba... This one was no different.
