DTR is an abbreviation for Desktop Replacement. Generally this abbreviation is reserved for the larger, heavier and more powerful notebooks that can be used as a replacement for one’s desktop PC. These notebooks typically have large (15.4″) screens, a non-mobile processor (such as a pentium 4 processor), weigh above 6 pounds and have a low battery life (usually 2 hours or less). Not everyone purchases notebooks for portability. Some people prefer having less clutter and a DTR notebook will offer them exactly that.
