Those using Linux on your laptop is the sleep, suspend, and hibernate functions working? That's my number one reason I have kept on using Mac OS X. The other being iOS development.
Yup (on a Thinkpad x220 + Arch), although I had to configure it. The ACPI daemon provides hooks, so you can run commands on certain events like "laptop lid close" or "power button pressed". I just added a single line to "pm-suspend" for those events. More info here: https://wiki.archlinux.org/index.php/Acpid
Honestly, I think it's dependent on the laptop hardware and distro though. I imagine Ubuntu has it working out of the box for most hardware.
