People who are new to computers now: Wow, look at all this cool stuff you can do with all of Google's services under just one account! All of my documents are on The Cloud and I don't have to worry about ever losing them! Oh yeah, ads just happen, you press close on them and you can use apps for free! What's a filesystem?
People who are in their 30s and grew up with computers: I hate people bikeshedding over whether Android or iOS is better. I hate people complaining about how the new Windows is so much worse and then using it anyway without trying to do something about it. I hate having to log in to accounts and subscribe to a monthly service to use a printer I own. I hate upgrading things just because the manufacturer stopped supporting them and neglected to unlock the firmware on the way out so I can keep using perfectly working hardware with community supported software. I hate being the free tech support in my family and I hate being conditioned to jump in and start helping when someone describes a problem.
