Yes, very easy. The advantages are that you can efficiently apply power to all parts of your pedal stroke, i.e. you can pull up as well as push down. Clipless with a decent platform and even somewhat rigid shoes present a night and day difference from toe clips/straps, and there is obviously no comparison at all to naked platforms.

There is a slight time penalty from standing as you have to position the pedal correctly and then lock into the binding, but this becomes second nature as you put miles under your bet. I find that, with said penalty, I can keep up with traffic from a stop light across the intersection. I also find that I can push higher gears in places I would other wise struggle to push.

If you are interested, I suggest a dual entry SPD pedal...not SPD-SL/Look/Time. SPD pedals and shoes are typically marketed as either MTB or touring products. SPD shoes are made such that one can walk in them much easier than other said clipless systems. I use road specific, single sided SPDs with Northwave Jet 365s with good results.
