My old laptop took 45 minutes just to load the basic memory test screen. @lucas_kelly is right, the waiting was built into the whole annoying thing. It felt like a waste of a good afternoon. Now it's over in a blink and I don't miss the old way at all.
Yeah, the "plan your day around it" part just felt like a hassle to me. It wasn't some meaningful process, it was just annoying. I was always glad when things got faster.
