Thanks.

Yeah, eleven years – and it had two major lightening-strike power surge hits in that time. The PowerMac which I had before that lasted twelve years. I know someone who had an Apple IIc that lasted nearly fifteen years. I have an iPhone 4.5 that's still working. My son has a gen1 iPad that works as well as it did new.

Meanwhile, my son's Lenovo ThinkPad crapped out after not quite four years.
