There were three bad experiences upgrading to 12.04 on my Dell Vostro
1720, but all have been overcome.

First the wireless. To get wireless working I had to blacklist the
dell_laptop module.

    - create /etc/modprobe.d/blacklist_dell_laptop.conf
    - put the line "blacklist dell_laptop" in it

Second, grinding slowness. I have NVIDIA hardware, and the default 12.04
driver version is 173.14.35. This is ancient. I used the "additional
drivers" program to update 295.40, and the slowness went away. 12.04 is
still noticeably "heavier" than 10.10 - my load average floats around
0.80, it used to float around 0.20. There is some suggestion that there
is a later and faster version, but I'm OK with what I have.

Third, Unity. Argh! OMFG! But a bit of googling got me a GNOME3 desktop
and while it will take a little getting used to, at least I have some
semblance of usability and configurability back.
