Is the HP-01 worth the effort?

[John Garza (3665)]

It looks nice but is bulky for everyday use and the chance of scratches or damaging the display would seem to relegate it to a 'storage box queen'. I don't own one, but have considered it over the years when one became available. I'd like to hear the comments of HP01 owners - maybe you can extol its virtues and convince me to buy one. But to be honest, if it had an ENTER instead of an equals sign, I probably would have bought one years ago. -J
