I don't like it.
Not because it messes with my sleep schedule because let's be honest, I barely sleep enough to be on a schedule.
It's all the time I have to spend resetting my watch and clocks. Luckily now a lot of appliances know and switch, but some don't because they changed the date that daylight savings was suppose to happen and so you have to do it twice. Once for the time it changed and then again when it was originally programmed to change. I don't think I have any of these devices. I did run into plenty of server issues at work this weekend though where some servers' time would change and others wouldn't then files had authentication issues because of the time discrepency. Y2K was so much easier.
Daylight savings also wrecks havoc on my fear of being late for work. I hate getting up early as it is and now I have no idea if the time I'm getting up is the right time since I use my cell phone and iPad as my alarm clocks. So I set 3 alarm clocks and hope none of them switch times incorrectly between when I set it and when I get up.
