I bought an asus U33JC and except for one major issue (frame tear) it works fine out of the box using 11.04 64bit, with some minor issues easily solved (suspend, upside down cam on skype, flash and java). The U33JC has optimus, but also a bios option to disable the Intel GMA. So I could use the on chip Intel GMA or disable it and use the discrete GF310M.

The major issue I have now is poor video playback. Frame tear occurs in every single configuration I tried: Either using the internal Intel GMA, or disabling the Intel via bios option and using the NVidia proprietary drivers or even using bumblebee. This frame tear occurs also on the desktop, but the real problem is that it's very noticeable on video, specially when connecting my HD TV via HDMI. I tested 720p h264 mkv videos and even low res xvid avis in totem and mplayer/Smplayer all equally poor. Using mplayer I tried several vo options, such as xv (intel? xv) and x11, and playback is poor on all of them. Oh, and I don't use compiz (don't care for it). Refresh rate is 60Hz, and should be the right one. It works fine with vlc on the soon to be transformed into free space windows7, but that's not an option for me. I used Ubuntu before on a laptop, but I usually use Gentoo, so I'm not familiar with the ubuntu distro.
The purpose of this laptop was to be my "tv media center" when at home and my work laptop for travelling (13 inch ! ). But it failed miserably on the first count. I'm still using my old celeron based Gentoo laptop with RGB out to my tv for that, still with much better results (it can decode only up to 720p, which is fine). But it is dying! I really don't understand why playback is so poor. Could messing with xconf be the answer?
EDIT: Here's my xorg log. NO VSYNC? Is this right? Please help.
