I just finished installing Debian on a new laptop with UEFI. It was very difficult! It didn't help that the computer was initially configured to use the small SSD as a RAID array for hibernation. Lots of repartitioning and reformatting drives, messing around with BIOS settings, etc. I've learned a lot about the modern boot process, LVM and chroots.
I accidentally hosed Windows, which was annoying: I didn't have the option of not having it included on this laptop, so I was going to keep it around "just in case". But then I realised I have never used the Windows 7 installation I had on my old laptop that I was keeping for the same reason. I feel kind of liberated*.
It's all up and running now though, and it's very nice indeed. Debian 8 works nicely with HiDPI screens out of the box, I'm enjoying GNOME 3, and boot times off the SSD are great. Now it's time to render some stuff!
