All the app store haters need to be aware that upgrading to OS X Lion will be through the app store only. If you got rid of the app store because you are paranoid about Storeagent you can't upgrade to Lion. You will be stuck in time. Good luck.
I'm not an App Store hater - actually I wouldn't mind checking it out. However, I do take my privacy very seriously and I do not feel comfortable having a background process automatically scan my entire hard drive and report the findings without my initiating that process. So, I am hoping that there will be a different way to obtain thew new OS (legally, of course) which, at some point, really will become a necessity for a myriad of reasons (bandwidth limits/throttling, slow DSL, system restore to bring up a few). The only info available right now is that you need 10.6.7 and the app store if you want to upgrade on day one - no mention of anything past that.
