Let me just say, I was WAY hesitant in rooting my Inspire cos of the process and how difficult it seemed to be compared to the Captivate (my prev phone). But I finally took the plunge and I'm so glad I did.
Like I said, it is sort of a complicated process, but there's tools and videos out there to help you if you're considering it. And remember you can always go back to stock rom. I'm personally using the
stock/rooted rom and haven't had any problems whatsoever. The only thing I don't have is the free hotspot capability, which other roms provide. I don't mind it tho cos I usually don't use it anyway. It's still hotspot capable, but I would have to get the added plan.
Feel free to PM me if you have any questions and I'll try to answer them to the best of my knowledge. Also,
this forum provides all the info you need to root and flash roms and has a pretty knowledgeable and noob-friendly community as well
