And now that everything is becoming mobile. What choice do you have? The only office suites that work on mobile devices are Office and iWork ...
Under a very narrow definition of "mobile".
Isn't that where VNC's come in. In a corporate environment why would you attempt to duplicate apps on a mobile device rather than simply securely tunnel to a local instance running all the standard apps on the internal network?
I guess one answer is: to use the cloud. But are corps really putting their faith and critical/sensitive docs in the trust of cloud based apps already?
BTW, don't cite techrights.org. They are one of the most unreliable sources of information on the net.
At least in principle. Not sure if there are critical omissions that might hinder interop. Devil's in the details, and such ..
We recently started the transition from the old Spreadsheet (Ruby) gem, which targeted BIFF8 format, to the Axlsx gem, which targets OOXML format. The results are so, so much better. Spreadsheets generated with the old Spreadsheet gem work presentationally, but features of Excel are broken when you open the resulting documents. We also ran in to issues when generating very large documents with lots of formatting. All of these problems are gone with Axlsx.
It's much better nowadays with docx format that is open and is used by default (for a few years).
