So since I've just turned 2000 miles on my car, should I go for a FULL synthetic oil?

Yes, kind of what I covered above.
It doesn't matter for Mobil 1; for all intents and purposes Group III-based oils perform identically to Group IV oils. In fact, many weights of Mobil 1 contain a large percentage of Group IV oil, making them true synthetics. 5W-30, however, contains mostly hydrocracked dinosaur oil, so it is not a "true" synthetic and would be considered a synthetic blend in any country but the US.
If you're not consuming any significant amount of oil (i.e. you haven't consumed more than half a quart over those 2000 miles), you're safe to switch to a synthetic. Otherwise, wait it out until oil consumption ceases.
