I somehow missed this update the other day:

We're pleased to unveil new updates to SkyDrive today! Here's a quick rundown of what's included:

  • More places. We're now live in 24 additional locations, bringing our grand total to 62 countries and regions! We welcome new users in Bulgaria, Costa Rica, Croatia, Czech Republic, Estonia, Germany, Greece, Hungary, Indonesia, Ireland, Latvia, Lithuania, Malaysia, Philippines, Poland, Romania, Russia, Serbia, Singapore, Slovakia, Slovenia, Thailand, Ukraine, and Venezuela!
  • Comments. You can leave comments on any file in SkyDrive and see all of the recent comments people have left for you.
  • Captions. A picture's worth a thousand words, but sometimes you need a few more. Now you can add captions and descriptions to your files and photos:

  • Click control.  When you click on any file, you can speed through all the files in the folder:

  • Larger photo previews - we've made the photo previews even bigger.

We’ve also added some other features like Details view and Photo Thumbnails view, plus more bug fixes (keep the feedback coming!). So have a look, kick the tires on all the new stuff, and let us know what you think. And as always, thanks for using SkyDrive!
