SkyDrive seemed destined to be another Microsoft also-ran product. Although introduced long before the current wave of cloud-based synchronization and storage services, SkyDrive had a number of frustrating limits, and comprised two separately named services (central and peer-to-peer file transfer) under one hood. Then Microsoft did something marvelous. The same week that Google released its long-expected Google Drive, Microsoft unveiled a thorough revamping of SkyDrive into an explicable and competitive service. (Microsoft lists the version that I reviewed as version 16.4.)
On the basics, SkyDrive compares to Dropbox ( Macworld rated 4 out of 5 mice ) and Google Drive. The service provides desktop sync software for Windows and Mac OS X (10.7 Lion only), as well as mobile access software for Windows Phone and iOS. A Web app also provides access to your storage, too, with drag-and-drop uploads in the browser. Uploads and syncs on the desktop happen speedily and without any tedious management.
However, SkyDrive offers zero Finder integration beyond a system menu item, and thats a problem for Mac users, especially compared to Dropbox and Google Drive. While neither service has a full-fledged native software client, such as that offered by SugarSync on multiple platforms, both provide cues. Google and Dropbox show the status of sync on an individual file and folder basis by updating an icon to show a green checkmark or other symbols.
Dropbox uses a contextual menu to pick from activities related to a file or folder, all of which are performed in a Web browser, but which at least take you to the right place. Google omits that. Microsoft omits both. You dont realize how much you rely on the icon cues and contextual menu option until theyre gone. I found myself repeatedly dropping down the SkyDrive system menu, which shows the current sync status, to see if uploads or downloads were complete.
The minimal preferences dont let you choose to sync only selected folders, either, a feature in both main competitors. Nor does it have Dropboxs option (missing in Google Drive) to pause synchronization or throttle bandwidth usage. For laptop toters, bandwidth can be at a premium on hotspot networks, or, when linked via a cell modem, expensive.
The Web app is very Windows-y, but it has a number of subtle touches and useful features that stand out in their own right and also outpace competing services. If you spend a lot of time using the Web app, you will find it more useful than Dropbox or Google Drives for previewing files, at the very least.
SkyDrives sharing parameters are abundant. You may share a link via email, Facebook, or Twitter, the latter two requiring you to link in your accounts. You can also generate a link. Links can be set to be read-only or to allow editing. Email links can be restricted to those who log in to a Live.com account. Finally, a file can be made publicly searchable. Shared files and folders show whats been linked via a right-hand sidebar, from which you can change permissions.
The one thing thats missing from this is my primary use of Dropbox: a way to share a folder with colleagues thats then synced with their desktop folders. In Dropbox and Google, sharing items adds them to the other parties main storage. (Technically, the services maintain a single copy, of course, but those files are copied to all synced computers.)
Microsoft makes shared files available in the SkyDrive Web app via a Shared link in the left-hand sidebar, but otherwise, shared items can be edited or viewed only via the Web, although they may be downloaded. Also, in testing, I was unable to get a shared file or folder to appear in another accounts Shared list, even though the link worked and was available for editing for that account when used directly.
The Web app previews documents rather nicely, and has a good leg up on other services. Images in any folder may be selected, and a small preview appears in the right-hand sidebar. Double-click and the image fills the browser, and provides navigation for looking at other images in the same folder. This works for sharing, too, where sending a link to a folder full of pictures lets the recipient view it as a gallery.
You can also directly edit files in the browser for Excel, Word, OneNote, and PowerPoint formats, as well as create new files of those types. This is a fantastic option for those who either dont own any or all of these apps or work with people who lack them. Options are less extensive than in full versions, but more than enough for editing. (A click on a button in the editor Web page opens the file in a desktop app if its installed, too.)
The SkyDrive app has a neat simplicity. It provides a straight forward view of items, along with the ability to preview those types supported in iOS, which includes Word and Excel, or downloaded and then opened in another app. Images can be viewed as gallery thumbnails or downloaded to local pictures storage. The app can generate and send links to items and folders, as well as upload photos and videos.
Microsoft includes a hearty 7GB of storage for free accounts, although previous users of SkyDrive had the option for a free bump to 25GB. The fees for more storage are relatively inexpensive. Add 20GB on top of existing a 7GB or 25GB free allocation for $10 a year, add 50GB for $25 per year, and add 100GB for $50 per year. Thats half of Dropboxs rate (revised in July), which are 100GB for $99 per year (or $10 per month) and 200GB for $199 per year (or $20 per month). Googles combined Drive, Gmail, and Picasa storage is slightly more expensive than Microsofts.
Macworlds buying advice
An argument for using Microsoft more mediocre products was once that it made sense if you worked mostly or largely with people running Windows. That argument isnt viable any more, as SkyDrives competitors perform as well under Windows as they do under Mac OS X, and SkyDrive both works well taken by itself and compares well to others. Still, its hard to find a single compelling reason to pick it outside of its superb use of the Web.
