I dual booted for about a year, and then I used virtual machines instead for the last year. Using virtual machines has been a LOT easier. I use Lubuntu on Virtualbox, and I don't plan on going back.

Things that annoy me about Ubuntu dual boot

* My Wacom tablet is terribly hard to configure on Ubuntu. * Flash support seems to be hit or miss in terms of out of the box functionality. Sometimes it works right when you install chromium, sometimes it doesn't * Windows weird partitioning. Windows will only let you have 1 or 2 of these special types of partitions on your HDD, and I somehow maxed out that partition count and couldn't fix it. It was very difficult to work with.
