Once again, I have to take issue with some of the other reviews. I can edit anything -- PowerPoint, Word, Excel -- in old and new formats. I long ago abandoned the effort to sync DTG to a desktop directly -- that hasnt worked well for ages. The cloud sync works fine for me.
My issues? First, printing. It doesnt. Not that I cant work around it by printing from any number of other places, but no. No printing.
And it shows its age painfully in Excel docs. Half my spreadsheets are uneditable due to "unsupported functions." Really. "Today()" is not supported. Or perhaps its subtracting two dates thats not supported. Or something else. I cant tell -- its not editable.
There are plenty of good, workable alternatives out there if you dont need direct-to-desktop sync. OfficeSuite Free is one. Microsloth Word, Excel, and PowerPoint are also available if you dont mind killing a gigabyte on your device and either paying MSs subscription or going through DropBox. If you need direct-to-desktop -- cant help you. Try transferring through iTunes is all I can suggest.
-- Old Review 4/10/2012 --
I had to write a rebuttal to the prior review stating that Docs to Go Word doesnt work with an external keyboard. My external keyboard (Zagg bluetooth) works perfectly with all three office components - Word, Excel, and Powerpoint.
I dont dispute that my respected fellow user has experienced problems, but I have never experienced such a problem with this or any prior version of Docs to Go. Therefore, external keyboard problems are not universal.
In other areas, Docs To Go has the best Word functionality of any iPad MS Word editor (I have tried some competitors). Its excel editing is adequate, as is its powerpoint editor. Its integration with Dropbox (my preferred cloud solution) works smoothly.
Is it as good as having a full-up laptop with MS Office? No, not yet. But with this, I can do 90% of my work on the iPad. Works for me.
