Sometimes I miss my time in IT as a net/sysadmin. I spent almost all night last Friday helping my friend do a mail migration and it was a lot of fun. Development isn't the green pastures I had assumed it was but it has certainly put my son in a nice school as the paychecks are higher.
It would be hard to go back to IT. The pay scale is much lower and I think it might be a dying industry with all this foaming about clouds and such. I'd also not have the luxury of remote work.
I gave up on hobby computing when I was in IT full time and I now spend more time doing hobby computing. I bet that'd change as well if I ever switched back.
