Pros: The device is small and easy to carry in a pocket. With its integrated battery, it is perfect on the go. Bought it to share pictures from a digital SLR with no wifi connection but it can also be used to stream music and video to any mobile device on the go. The iOS app would need major improvements but as the device supports the Samba protocol (SMB) you can use any app using that protocol (ex.: FileBrowser for iOS).

Cons: The performance is slower with the Macally device than with my portable ftp router. Expect some delays if you want to browse through huge pictures (+16 mpix). But it is much more portable than my previous device so I still prefer the Macally. I hope that the slow performance can be improved through an app or firmware update.
