I believe that a tablet section is necessary but there has to be some rules as to what are classified as tablet apps. I suggest you look at Tablified.com to address the issue of what is or is not a tablet app. These guys did a pretty good job of finding tablet apps and they are adding more all the time. The difference between this site and some of the other lists floating around on the net is that the apps displayed on Tablified.com are tablet SPECIFIC apps. Meaning that the UI of the app must be a lot different than a phone app. I guess they have some criteria thst must be met before adding an app because I tried sending in a few apps for them to add but a couple were denied because they didn't meet the specification to be called a Tablified app. If you're not gonna bother distinguishing apps between tablets and phones then theres no need for a tablet section. If you use the apps displayed on the site then I think its a good idea, if not, then there's no point.
