For general usage there really is no reason to get an SSD or hybrid, if you sort out your HDD properly then there's no reason for it to be giving bad latency.
Yeah, I sorted things out with my disk's autostart items and now I'm booting in 74 seconds not counting POST. I guess this is much better now, huh?
Speaking of replacing the laptop, you don't need to for almost every laptop out there if you're using laptop drives or SSDs: their power consumption should be still within connector limits. 2.5" drives don't drain as much power as their 3.5" cousins.
