That’s likely to be the iPad at it’s best: the touch interface that delivers the index-card organization skills of the prior century, without all the erasing and the need for a full boardroom-sized table.

Infinote is going to sell for just $2.99, priced as any app for the iPhone. On the other end of the pricing scale, The Omni Group will be releasing its flagship OmniGraffle visualizer and process charting tool. While Infinote is certain to be worth its price, it will be interesting to see the takeup on an iPad program priced closer to Mac software levels.

Having worked with the $99 OmniGraffle a while on our Macs, we can testify to its endless ability to create the likes of mind maps, org charts, story flows for creative teams, even process diagrams for manufacturing if you’re stubborn enough. Graffle has ample flexibility on the Mac, and the company’s development team boasts one of the most loyal user bases and cleanest reputations in the Apple community. Their heritage comes from the NeXT community, which created the foundation for the Mac’s OS X.

For many years OmniOutliner was bundled in with Mac software, as recently as the MacBook Pro systems. Today there’s a handful of free apps available for download from the Omni Group site. And the Mac version of OmniGraffle can be used for two weeks for free as a trial. (We’d recommend tapping the Graffletopia site if you’re taking the 2-week trial, since it provides a nice jump start with shared stencils.)

Graffle, and perhaps to a lesser extent Infinote, will show off the new interface of the iPad while they help boost productivity. While the appadvice.com list is currently overrun with games like Flick Fishing, business apps as essential as organizers and databases (Filemaker’s Bento is on board; not exactly a surprise from the wholly-owned Apple subsidiary) will be certain to emerge over the first few months of the iPad’s life.

In short, the iPad’s browser will be Safari and probably nothing else, since Apple wants to control this aspect of the iPad experience. But this Safari demo shows how the iPad can be a powerful research tool for gathering information from those Web business resources which don’t have a dedicated iPad app yet. The advantage to using this rather than a MacBook lies in the ability to share your results by just passing the iPad around — something cumbersome with a laptop, or even a netbook.
