For the longest time I didn't root and I was quite happy and thought why would people root and risk bricking the phone. That's just crazy!
Then one day I found out an app on the Market that I really wanted and needed, but I couldn't get it because I was running out of space on the phone. Now the choice was... do I delete other apps (which I use constantly) so I could fit this one app in, or do I root so I could run many more apps from the sd card?
So I spent the next 2 weeks doing research on rooting, moving apps to sd, linux, pitfalls, etc, weighed the pros and cons. Then I decided... I'll give it a shot and root. Other than an occasional wipe, rooting didn't harm my phone. It actually improved it a lot.
Are there days I'd like to go back to non-root status? Sure... when the phone acts up. But the pros on rooting for me way outweighs the cons any day.
