I've just tried using Kies. It asked if I wanted to upgrade the (Kies) software and I did. But it runs incredibly slowly. It took about 10 minutes to connect to my GT8010. I then tried backing up s planner and s note and gave up waiting for it. All the while, whether doing anything or just it sitting idle, it runs my laptop CPU at almost 100% What on earth is wrong with this thing? Anyone else have any experience. Also, any way to revert to earlier version of software? Thanks.
