If you need UMS you'll have to buy a phone with a microSD card slot "or a separate partition like Nexus S.
...and that's the unfortunate reality of it. Again, a tough compromise -- one which Google saw the benefit of a single massive block of usable storage vs. the partitioned approach that improves usability AND allows apps to access all available memory.
But it's important for the SD-card lovers to keep in mind that just because this is Google's vision, and just because the Nexus eliminates this option, doesn't mean that ICS won't support it on other devices. It will. So if it's an important feature, there should be Android 4.0 devices with removable SD (or at least UMS support) in the first half of 2012.
I recall that Dan also wrote that it is possible to partition the Nexus' memory (the /sdcard directory is just that -- a directory -- and not a separate partition). But I don't know if partitioning a portion of the 32GB will have the desired effect of allowing it to be unmounted and handed off to a PC or a car audio player.
