I just started using SkyDrive and I really like it. It's simple and fast, and even to a person like me that generally dislikes and distrusts the cloud, it's great to use.
I use both as well but have found that SkyDrive syncs up better/more reliably.
BTW, what happened on Tom's? My account seems to have lost all it's settings...
"To make the combined data management easier, Google will be making some updates to the Drive storage page. Users can simply hover over the pie chart to see a breakdown of their storage use across Drive, Gmail, and Google+ Photos."
The link provided in that sentence doesn't show a pie chart for me. Am I missing something?
