It was great to work with Metcalfe. I have two funny stories to share.
I was on the Macintosh network os client team. For whatever reason (maybe he was annoyed that Apple copied so much from Xerox) Metcalfe didn't like Macs. In this era Macs used Apple's proprietary AppleTalk/LocalTalk network. We did a demo for 3Com execs using a large external monitor connected via a single black coax cable that looked just like thin-ethernet. He got excited for a moment and came right over to look at the Mac and was very disappointed to see the cable attached to a display! (3Com was working on Ethernet cards for Mac at the time but they weren't ready at the time of this demo.)
For those too young to remember: there was an SF Bay Area baseball park known as Candlestick Park that was briefly branded "3Com Park" -- to the great annoyance of SF Giants fans. During one interview he as asked if in the early days of 3Com he would have done anything differently. He said, "I would have named the company 'Candlestick'!"
Ha! He makes the Candlestick remark in this interview too.
