Summary: Beyond specific verticals and specialized jobs, tablets are facing a usage problem with business professionals. They aren't winning as companion devices or convertibles, as we discuss in this week's Monday Morning Opener. By Larry Dignan |March 2, 2014 -- 23:00 GMT (15:00 PST) Image: iStockphoto I'm packing for a business trip and once again the game of "do I pack the tablet?" starts anew. I need the laptop for work, need the smartphone because it's the one thing you can't leave home without and add the Kindle because the screen is easy on the eyes for reading. Does the tablet go along for the ride? Increasingly, the answer is no. The tablet is fun for consumption and that may work for many folks. But it's hard to argue the tabletthe 7-inch to 10-inch varietyis a tweener device. Tablets aren't quite mobile enough and not quite productive enough. Tablets are companion devices when I increasingly want to vote a device or two off the island. To date, I haven't quite found that convergence device, but it's pretty clear the tablet isn't it. For a tablet to be a convergence device you may need a keyboard, a smartcover of some sort, and maybe a few adapters. Add it up and all you've done is cobble together an ultrabook or MacBook Air.

The ElitePad has a bunch of accessoriessmart jackets, battery, adapters, covers, docking stations and other goodies to turn this tablet into an enterprise IT powerhouse. Derek Everett, director of worldwide product management for commercial Windows tablets at HP, was explaining to me how "not one size fits all with tablets." ElitePad is certainly flexible. But I had to interrupt him with: "At what point do you say screw all of this and just buy a laptop?" Everett explained that certainly some people see tablets as a companion device. Others see tablets as notebook replacements. However, I'd argue most of us don't see them as either. And that's the problem. For some business casessales, marketing, and customer service come to minda tablet is fine. For the rest of us, tablets have a few issues. The larger issue is that the so-called convertible movementtweener laptops and tabletshasn't delivered that business home run yet. So for now, the tablet is voted out of the backpack. You can only lug around so much.
