When it comes to viewing and editing Microsoft Office products on your iPhone/iPod Touch (primarily Word and Excel), there are essentially two apps that lead the way: QuickOffice and Documents to Go. Each have their own strengths and a user base that prefer one over the other. If you’re a heavy PowerPoint user however, choosing DataViz’s Office suite just got easier. With the latest 3.0 update of Documents to Go Premium, users can now even create/edit PowerPoint slides right on their trusty iDevices. For road warriors who do their share of presentations, this new ability could prove invaluable indeed. Another great new feature found in this update is the added support for Gmail attachments. That’s right, you can now edit/view files directly from your Gmail account. For those who don’t require PowerPoint, check out DocsToGo, which has less features but a more affordable price tag ($9.99). Complete app details after the break.
