Initially it was just general boot up, sometimes wouldn't go past the grey screen. Others it would make it to the home screen and I couldn't click anything, or apps would continuously "hop" without launching. I'm fairly certain it was a hard drive issue. Ran the verify disk plus repair which fixed an issue that was discovered but I'm still skeptical. The general sluggishness has all but gone away but there has been a couple of manual reboots that we're needed.
Not exactly sure though. Any insight?
Sounds like hard drive to me. Have you reinstalled the OS? If its hard drive, which it sounds like it is, it's either software related or hardware related. You can rule out software by reinstalling the OS. If the problem goes away, excellent. If not, I would replace the hard drive.
