My 1130ag died and I bought this as a replacement. The overall construction and design of the 1600 is better than the 1130 though the 1600 is uglier. The 1600 runs sooo much cooler than the 1130, plus it has rubber feet to properly sit on desks, the 1130 does not.
Rubber feet; Runs relatively cool
Doesn't come w/ AC Adapter; Not as aesthetically pleasing as 1130ag
