DESKTOP or LAPTOP

Laptops definitely. Because I have been using them @ work & I found them to be better, faster, efficient in TAT than a desktop. However the downside is the RAW power of desktops outrun all Laptops [except the latest ones w/ DualCores] and the heat Laptops generate sometimes is the cause of their slowdown. But Laptops can be used anywhere & can be carried anywhere, where desktops cannot go...

Desktop. There more powerful, cheaper, and easier to fix and replace parts in them. There also more stable, and require no charging/batteries.

Desktop - only because of the keyboard.
