OK, so unless I am just unlucky I should not have a problem then. I am rather averse to hardware problems on tablets, my last computer had an unrepairable SSD after only twenty months.
I understand what you are saying about repeatedly plugging in USB drives. That is why I am so satisfed with the design of my new (very cheap) USB hub —– it has 7 ports each with its own switch and light. I leave my usb drives and two SD cards plugged in more or less permanently and just switch them on / off as required, so no wear at all. I was going to buy a similar one for USB 3 but will wait for the machine to be delivered as it may not be required.
