Is the HP-01 worth the effort?

I have 3 HP-01s, ranging from museum quality to "daily beater" to "Panamatik rebuild/restore". It is, quite simply, an absolute monument to 1970s electronics. The fact that HP made this for the consumer (prosumer?) market is incredible. Never before (or for a long while after) had such sophisticated electronics functionality and fabrication been available through retail.

I do wear mine from time to time. They are extremely comfortable and wear well. Yes, they are hard to operate (other than basic time/date displays). Plus you don't want to lose the bracelet-mounted stylus. I do think we should wear these!

If you're serious about vintage (HP) electronics I think it's a "must-have" - if you can get one.
