baaah....I have held off on installing ANY beta releases of Lion. I actually have a dev account and just don't like messing with OS betas on my primary machine because I have too much to lose if things go wrong on this machine. I have an iMac that I used to put the OS betas on but its boxed up in storage because our house burned down in March and things are still not together so I use this MBP i7 for everything in my life, the thought of a beta compromising could really hurt me....so this has been killing me not being able to play with it AT ALL and all week with the release dates sounding like this day or that day or this hour etc...I've just been getting so damn excited that I don't think I can wait any longer! I've already downloaded the latest Lion....and I'm so close to pulling the trigger. I guess my only concern is that if I do it, I'm sure I can upgrade and things will be fine - but once the legit final version comes out, will I have any issues going from 11A511 to the final retail? Any thoughts from those with experience would be much appreciated. I just don't want to do it otherwise. I've been running iOS5 since the first beta and that's been sloppy, but I know if I have to wipe my phone I'm OK. If I have to wipe my MBP it's gonna hurt me a bit to have to rebuild.... ::::: This "NO DISC" "App Store ONLY OS" for the first time ever.... is what's scaring me. We've never done it like this before...I just don't know what to expect with the transition from 11A511 to Final. It'll probably be a simple upgrade...just nervous.
