As expected, the launch of Office 2010 has been met with a barrage of criticisms from rivals with Google leading the onslaught with Salesforce going as far as extending sympathy to Microsoft.
The Register met up with Salesforce.com's EMEA director, Tim Barker, who bluntly said that "[Microsoft] Office sucked productivity out of people" and pointed out that Microsoft came to the cloud computing market late with Office Web Apps.
Salesforce claims that it doesn't have any intention for the moment to launch a rival to Office 2010 but we'd bet our bottom dollar that a partnership with Zoho (or even an acquisition) might happen soon.
Speaking of Zoho, the online outfit had a post on their blog called the "next evolution of Office suites" and compared the current desktop version of Microsoft office to a 1980s Stereo cassette player before adding that "Office Apps componentised and integrated into Biz apps" is the way forward.
As for Google, they're already using their clout to encourage people to upgrade to Google Docs rather than to Office 2010 and have already posted a rather extensive checklist that compares both offerings extensively.
It goes without saying that Microsoft's main rivals will be gunning for Office 2010, which is the company's second biggest revenue earner.
