Entelligence is a column by technology strategist and author Michael Gartenberg, a man whose desire for a delicious cup of coffee and a quality New York bagel is dwarfed only by his passion for tech. In these articles, he'll explore where our industry is and where it's going -- on both micro and macro levels -- with the unique wit and insight only he can provide. There was a raging debate going on last week at Engadget HQ over the role of dedicated ebook readers that spilled over on to the Engadget Show. You can watch the show here, but essentially big boss Joshua Topolsky and Paul Miller feel that the new Barnes and Noble Nook is going to be a hit -- the one machine that gets suburban moms to buy. On the other hand, Nilay Patel, rationally (as he agrees with me) says it's not going to happen and there's no mass market for dedicated ebook readers. I'm going to weigh in and say Nilay is probably right.

Now don't get me wrong, this is not entirely an integration vs. convergence story. I believe there's a market for dedicated devices: cameras have not been displaced by music phones, media players have not been displaced by music phones and ebook readers could serve bibliophiles, especially those who travel a lot. However, mobile reader apps like those from Amazon and Barnes & Noble can easily tap into more casual markets, allowing users to leverage the investment in screens they already own instead of buying a dedicated device. That's one reason why I think it has been important for Amazon and B&N to get their ebook platform onto as many devices with screens as possible, and why Sony's making a mistake by ignoring the opportunity.
