There's no native SkyDrive app for Android users, which gave me pause--while I do most of my actual work on a PC, I want to be able to at least read and send files on my phone. That doesn't make me particularly unique these days. There are native apps for iOS and, of course, Windows Phone. That said, Microsoft features several third-party apps for using SkyDrive on an Android device. I tried Browser for SkyDrive (Free). As a number of Google Play reviewers note, it's not the prettiest thing. The jury's still out, but I wouldn't necessarily want to rely on this for regular business use. I found another free app, Android Explorer for SkyDrive, was easier to use and had a much cleaner interface. Android compatibility, while it exists, is an area where SkyDrive loses some points, particularly compared with Dropbox and Google Drive.
