Create option to auto sync with Skydrive with no compression as soon as connected to WiFi.
The current auto sync with skydrive compresses pictures before uploading. This way still no real backup is made. Since skydrive offers 25gigs more then enough space is available for backing up in full size. Create an option to 'only upload to skydrive when connected by WiFi' and an option to choose to compress or not.
Great suggestion, but these are consumer features – and not developer platform suggestions. As such, declining this idea to give you back your developer platform votes.
