Electrical & Computer Engineer but mostly software and software requirements by prior jobs.

Worked with microprocessor & support boards, mini computers (DEC/VAX), unix (Sun OS & other) boxes, Apple/Mac power PC & Intel, and varieties of PCs with DOS and many versions of windows.

Cellular infrastructure boards & software support for both analog and digital cells & switches.

Currently work on Dell laptop software and hardware repair supporting Federal Mogul sales force.

Currently using my son's hand-me-down MacBook Core 2 duo.

Joined StackExchange when the MacBook wouldn't boot up. Recovered via info here or another Apple site. No HD errors found so I think the 160G hard drive was just too full with 16Gig left but recovery from Time Machine backed up a day earlier got me running again.
