It always used to be DELL computers for me!
Not one but 3 desktops I have bought from Dell - and all great deal!
This was the time when DELL distributed their desktops only online. One of the early adoptors of the online store.
Since then things have changed and we do see DELL desktops and laptops in Staples (or Bestbuy, too?)
Bottom line - The performance is really good.
Though they have big competition from HP, Asus, Toshiba - they are good for sure.
