Hi, I'm a beginning dev and have a stupid question but would like your advices I currently only own a laptop and iPhone. I test my stuff on these. I have created a partition for Lion since DP1. I haven't tried iOS 5 yet. However now I'd like to use more often Lion instead of using SNow Leopard and sometimes boot into Lion. Same for iOS 5 since I would like to test my App with the iCloud stuff. My question: do you consider it safe to install Lion as my main and only OS from now on and iOS 5 as my... well only OS on my phone? So I can test my stuff more efficiently but that also means I need my computer and phone to work correctly if I want to simply do regular work. I'm a current MobileMe subscriber so the transition to iCloud should work without interruption of email etc, right? Thanks!
