MyFiles is a feature rich application. Although, it is very much like Windows Live SkyDrive.
To become more superior than SkyDrive you need to make just a few adjustments.

1. Consider releasing a Web-App that would allow me to put access to my Acrobat.com information via
the web or any one of the many social networks.

2. Create a Windows Sidebar Widget with one click access to Acrobat.com

3. Develop a way which allows users to upload multiple folders with multiple files.
(SkyDrive lacks this feature as well, many of us have multiple folders containing multiple documents,
creating the capability to upload more than just the contents of one folder at a time would
make MyFiles a leading innovator)

4. Compete with SkyDrive by offering atleast 25GB of storage

 
I look forward to seeing Acrobat.com grow!
