Despite the grumpy headlines coming out of the Consumer Electronics Show this year, it’s easy to get excited about the prospect of hitting Vegas and checking out all the hip, new gadgets, along with the occasional useful new piece of business technology.

For those of us who do tech for a living, there are, of course, a world of more focused and vertical-specific trade shows and conferences that are a little easier to rationalize in the expense budget. If you are considering attending a conference or two in 2012, here are some candidates where you can share ideas with peers and get courted by tech vendors. Oh yeah, there probably will be some neat chachkes, too.

We’ve broken the shows out by category, for review by your team. We’ve included only shows occurring in the United States, and some obvious candidates (such as Gartner’s Symposium/ITXPO) have yet to set their 2012 dates and locations. And, of course, this is only a small sampling of what continues to be a lucrative trade show industry. If you know of or are involved with a show you think would be useful to your peers, please add basic information and a link to the show’s site in the comments section of this post.
