We own, I've been. It's fun (I guess about as fun as any annual meeting can be), but we can only get up to 4 credentials to get in, and there are 6 of us. It's held at the Century Link/Qwest Center. They have it in a large arena with a q-and-a session. I recall the year I went, Bill Gates was sitting down in the front somewhere, also. They have displays set up downstairs with the products they own. People also take advantage of the sales at Nebraska Furniture Mart and Borsheims Jewelry that weekend. Those retail stores are quite a distance from Century Link. The one thing I like about Berkshire Hathaway and Warren is the philosophy that he does not invest in something that he does not understand--like technology.
Prior to when the 2015 meeting rolls around, go check out e-bay in February, March or early April. Berkshire and others will normally have some credentials for sale pretty cheap (and I mean cheap) there which will allow you to attend the meeting, if you don't want to buy one share of stock.
