Once upon a time, I owned a 19" CRT that weighed less than a typical 17" CRT. Such good fortune. Still, I never did have the courage to carry my tower on one hip and my monitor on the other (and everything else in a backpack), so I guess it didn't really benefit me that much after all.

You're damn right. Imagine carting a CRT around and then only staying for half a day. Ha!
