Healing, jumping, attacking buildings, attacking air (as well as ground) are all things that their tier 1 - 1.5 units can do. Tanks can be in siege mode or in tank mode, vikings can be in the air and the ground. Terrans seem to have more abilities with their units, and have a greater flexibility with what the units can do. Probes don't get consumed, or even work for the creation of a building. With the fact that a single probe can queue up 10 buildings as quick as he can move to new sites, this gives the Protoss the ability to respond to building needs quicker than other races.

With their larvae, you will probably have extra larvae and if you need extra units, you can get them quicker, because in midgame, you might have 10 larvae sitting around waiting to be morphed into something. Each of the different races has the ability to react better using different options: I agree with willful wizard, he's got a good answer, but I'd like to add my two bits here too: In the end, it doesn't matter where you start as long as you put in the time to learn it. Also if you come from more traditional RTS, you might find Terran to be more familiar. That said, I started with Zerg, and I really enjoy them. This emphasis on a tier 1-1.5 (Zealots, Stalkers, Sentries) often makes life easier for new players. The bulk of a Protoss force comes out of the Gateway, one of the first structures you build. Photon cannons provide both air and ground defense making them a nice staple for new players. This can mean less micromanaging is necessary.

Protoss units tend to be tougher and more expensive than their Terran and Zerg equivalents. Instead they start buildings and the buildings build themselves Protoss have a number of things that make them friendly to new players: This was closed for obvious reasons, but I'll repeat the answer I wrote: There was another thread which asked why Protoss was the easiest race.
