Hi,
I installed Skydrive for my wife and bought additional 20GB. We use the skydrive on a x64 Windows 7 laptop which is always connected via WIFI.
The connection is perfect and the internet connection is stable with a 6Mbit upload. The problem however is that certain files and folders are never synced online. The program is taking quite some memory. Viewing the local skydrive folder via file explorer also seems slow and thumbs are not created unless we manually stop the Skydrive app. The general feeling is that if performance is not better, we will try to get a refund as this is not working for us.
