Mine is several years old, but also on the original cartridge, though it's down to claiming ~300 pages to go.
Some years back you may recall I had a problem with Dell. The PC I had them ship directly to my father wouldn't boot up.
After much run-a-round with "English-speaking next available agents" I did some snooping, determined the VP of "support's" direct street address, sent him a FedEx Letter.
Said some of my usual "kind words" ;-)
Next day they sent a technician to Huntington, WV, to my father's house to fix it.
And this will really get you... it wouldn't boot because the hard-drive they stuck in it, and obviously didn't test, had Win95 as the OS :-(
I'll watch or it ;-)
