But damn, yes, the Store makes life so much easier for every user.
I can’t tell you how many hours I have spent trying to dig through old emails and guess at old passwords to get registration credentials for old software. That used to be the sole reason that I never deleted software from my Mac.
Just before the Mac App Store I started to store this data in Yojimbo so that I could delete apps, but the Mac App Store just makes deleting apps you don’t want anymore a no-brainer. So what if I have to pay for upgrades, at least I have a full, working, archive of every app I bought.
