Microsoft Producer for PowerPoint (formerly Microsoft Producer for PowerPoint 2003) used to be a downloadable application but nowadays you can only use it online. Microsoft Producer for PowerPoint 2010 is simply designed to allow you to access your PowerPoint files on the move from wherever you are in the world as well as create basic PowerPoint presentations for free.

PowerPoint now works via Microsoft's SkyDrive and so to access your PowerPoint presentations, you'll have to upload them first which requires signing-up for a Windows Live ID. After that, using Microsoft Producer for PowerPoint 2010, you can share documents with others, collaborate on them and create basic PowerPoint presentations with ease.

There are several templates to choose from and the interface is based on the desktop version with the Office ribbon to guide you through the various functions on offer. There's also a button that takes you instantly into the desktop version if you have it installed.

Microsoft Producer for PowerPoint 2010 is an excellent albeit slightly limited tool to create PowerPoint presentations online for free.

There are three main apps available in Windows Live Office: Word, Excel and PowerPoint. With them you’ll be able to work on text documents, spreadsheets and presentations like you do with Office. Obviously you won’t have as many tools and options as the standard Office, but on the upside, you’re able to work on your documents pretty much anywhere, at any time, as long as you have an internet connection.

The three apps included in Windows Live Office feature a similar interface to that of the desktop apps and are quite self-explanatory. You can not only create and edit documents online, but also download files to your computer, share them via a link and upload files from your hard drive. Regarding the latter, Windows Live Office offers up to 25 GB of free space – SkyDrive – to store your files.

Summing up, Windows Live Office may be a stripped-down version of the original productivity suite, but it works perfectly fine as an online tool for daily document management and editing tasks.

Windows Live Office is the perfect companion for online document, spreadsheet and presentation editing.

If Microsoft isn't afraid of Google, it should be. Microsoft Office has been ingrained in the minds of millions as the default document editing suite for years. Google Docs, now called Google Drive, is a direct competitor to Office.

While Google Drive isn't as powerful as Office, it contains enough features for the average consumer to not miss Office at all. Best of all, Google Drive saves all your documents in the cloud so you'll never lose a document. Google also has a suite of mobile apps on iOS and Android so you can view or edit your Google Drive documents on the go.

When Google Docs turned into Google Drive, it introduced the ability to save any type of file. Users can now create folders and fill them with whatever files they want, directly competing with Dropbox and Box.com. All files will be synced as Google has a desktop application for Windows and Mac.

There are also powerful collaboration tools in Google Drive that allow you to invite other users to view and edit documents. There's a commenting and revision system so you can see who did what. This is great for people looking to work on a project together.

Overall, Google Drive is a great office suite and cloud storage alternative. If you use Google's other services, you'll love Google Drive.
