I just recently purchased a Blichmann 14 gal. conical as well. It greatly simplifies my process for 10-11 gallaon batches. I use to have to use two carboys. The process was Primary -> Secondary -> Bottling Bucket -> Bottles, or Primary -> Secondary -> Keg. Multiplied by two. I know there are other, less expensive ways to simplify (no need for secondary, larger, non-conical fermenter, etc.). This works great. I have leg extensions and casters, and it just rolls into my "fermentation chamber" (I like that term better than "downstairs bathroom"). Now, the only transfer is once to the kegs, or I bottle right from the racking port on the fermenter. Instead of transfering 3 or 4 times and cleaning 6 vessels in the process, I only clean one. Stainless Steel is nice - I don't worry about scratching it when cleaning, and it does not absorb and retain the wort smell that plastic can. I have come to loathe dealing with glass carboys.
No question you do not need a conical to make great beer. However, if it fits with your process it can be a great addition to the home brewery.
