It's a devkit, not for general release. Microsoft has already addressed why the FoV is narrow, and it has to do with battery life and power needed to process the scene. So the wider FoV will come when battery tech and processing power catch-up. I've used a Hololens, yes the FoV is off-putting, but the technology itself is incredible. If I had $3K to throw around, or if I were a big enterprise looking to invest for various research using Hololens, I'd say it would be worth it.
