Just a physical difference AVR chip package used, Uno SMD = surface mount 328p chip, standard Uno = DIP packaged 328p chip. Not other software or hardware difference from a sketch or shield perspective. Normally the DIP version is more popular as it allows one to remove and replace the 328p in case of chip damage or to move the chip to a standalone project.

Have the changes made to the Uno R3 also been applied to the SMD Uno yet? IIRC the original SMD Uno was similar to the Uno R2.

I don't believe so and I suspect the SMD will most likely not be updated in the future. It was a short term solution when the Uno board was first released and there was some kind of world wide shortage of the DIP packaged 328p chip. I see no advantages at all for the SMD version Vs the standard version of the Uno board, only disadvantages.

Agreed but I don't see why you cannot update the bootloader with an ISP or another Arduino.
Certainly you can write whichever bootloader you like to any Arduino board.
