Umm, the speed of the onboard RAM is WAY faster than the crappy SD card. No way would I want to run the OS off there.
I haven't tried recently, but a while back I ran a rom with maybe half my apps or so on SD...
Didn't notice any difference in performance. I don't think it gives you "extra ram" to utilize because I believe the internal memory is partitioned for system memory and apps storage. I may be totally off-base, but in System Monitor it would show like 160mb allocated to system memory, 90mb allocated to cache, and @ 250 or so allocated to apps. I realize it adds to like 512mb, don't really understand it.
As far as I can tell, the only reason/advantage to moving apps to SD is if you are running out of internal storage space.

Correct me if im wrong, but that issue with mounting the sd card to your pc is normal.
If you apps are on your sd card, and you've mounted your sd card, your phone is going to have trouble accessing the sd card.
Kind of like when you mount your sd card and try to use a file manager on your phone.
Also, there isn't just one single variable (i.e. free memory) that affects performance. Consider the overall picture.

I am by no means an authority on any of this so please correct me if I'm wrong here.
Once you mount the SD card to the PC then the phone no longer has access to it until you dismount it from the PC and it is automatically remounted to the phone.
Unless you are using an SD card with a high speed rating (class 6 or higher) then larger apps might be slower to load form the card rather than the internal memory, and from what I understand running the OS from an SD card would be a sluggish hell the likes of which I would only wish upon Steve Jobs.
The benefit to installing apps to the SD card is to save space on the internal memory which becomes an important issue if you have a lot of apps. There might also be a benefit to having a separate partition on the card for apps that will allow you to restore apps and app data if you have to wipe the /system and /data partitions, but someone else will probably be able to give you better advice on that.
By the way, I have no affiliation whatsoever with this app or the dev, I just happen to love it.

I posted this in the LauncherPro Redraw thread here, but I'm under the suspicion the launcher API (meaning any launcher) enumerates the sdcard due to the Apps2Sd feature causing the launcher redraw people are experiencing. After moving everything back to the phone I've had no redraw issues, but it's only been around 5-6 hours but normally by now I would have had a redraw lag. I'll know more by the end of the day but I'd still suggest only moving apps to your sdcard ony if you are short on memory. As saif the internal memory is by far faster.
