Do NAS vendors ever actually use their equipment? My guess is no. I'd love to know if the CEO of 3Com and US Robotics actually use ISDN from home and call in to their office using 28.8 modems. They're probably too busy. My sense is that few people at Shiva actually dial in from home. I'm sure the folks at Ascend don't use their products (because if they did they'd notice all the bugs and the fact that their boxes reboot all the time).
