if you live in a town that has an apple store, sure, take the plunge. If not and you're on a windows machine, id be weary... I was on 1.1.4 and tried to go straight to 2.0.1 and iTunes couldn't finish the update... Eternal spinning wheel on the logo screen. I drove two hours to the apple store to get the phone working and he said just wait until the next iTunes update before I attempt another resore or update. They got me to 2.0.1 at the store and it's cool and all. Apps seem a thousand times more stable than installer and the jailbreak thing.
