normally I'd agree 100%, but the KF is so finicky about showing up as a USB device in Windows, I prefer to never connect it , for a stress free experience! so I use calibre cloud/ calibre companion for books. Amazon cloud to access photos taken on Kindle...
otherwise it's a voodoo dance of do I put KF into standby & then connect, or vice versa... or do I need to fully power KF off, then connect then power on ( which is what I had to do to get Win 7 to install the correct drivers, initially.... or will it just work, out of spite & to prove me wrong
So to save me having to do that, how long do you reckon a 1GB file copy should take via USB, from PC to KF ? I'd expect something comparable to writing to a USB2 memory stick ( which can be not very fast )?
