Good advice.
But last I checked 1500 connections worked out to once a day, every day, for over four years. In a high use model four times a day for a year.
Where's this 1500 connection limit coming from. The fragile part of the device is the re-writes of the flash memory. If that lasts 100,000 times what part is wearing out after 1500 connections? I've never heard of this limitation and I can't find any other reference to it.
======================================
After doing some more looking I did find that the manufacturer of the USB connector itself must guarantee at least 1500 connections. I couldn't find any data on what the actual failure rate.
