Office suites in the cloud: Microsoft Office Web Apps versus Google Docs and Zoho

Microsoft Office Web Apps: Office, everywhereAlthough Google Docs and Zoho are both flawed, Microsoft could hardly have expected to take this competition lying down. The Redmond-based giant is currently in the process of readying a fully Web-based version of its Office productivity suite, due to launch simultaneously with the release of Office 2010. While the Office Web Apps are currently only available as a Technical Preview (with a formal beta program to be announced later this year), they're already shaping up to become a formidable challenge to Zoho and Google Docs.

Nowhere is this more evident than when you import your first document into Word Web App. Unlike its competitors, Microsoft's online suite reproduces .doc and .docx files with absolute fidelity, down to the smallest detail. The results are jaw-dropping. Fonts, page spacing, headers, footers, auto-text entries, footnotes -- everything appears exactly as it does in the desktop version of Word. Images show up where they should, even when placed above or behind text. Documents that mix page sizes, or that alternate portrait and landscape modes from page to page, load correctly. And, most miraculous of all after experiencing the competition, printing is flawless.

The PowerPoint files I tried yielded similarly impressive results. Images retained most of their quality, and text remained where it should. And unlike Google Docs or Zoho, the PowerPoint Web App managed to preserve animated transitions between slides.

You'd be forgiven for assuming that Microsoft relies on ActiveX controls or other IE-only trickery to achieve all this, but you'd be wrong. Internet Explorer users are offered an improved file upload UI, but other than that, everything renders the same in all of Microsoft's supported browsers, which includes not just IE 7+ but Firefox 3.5+ and Safari 4+, as well. Just for fun I tried Google Chrome, too, and even though that browser isn't formally supported, everything looked fine. That's it; no add-ons or plug-ins are required -- but if you do install Silverlight, fonts look crisper and document load times improve somewhat.
