A320 family v 737 family:
Look at how the front of the tail looks like where it attaches to the fuselage.
Nice looking = A320
737 classic v 737 NG
737 NG= with winglets
737 classic = without winglets
146 v 747
Look at the wings. High wing = 146, low wing = 747
cruel but very funny.

The Airbus A380 can be identified at a number of airfields around the world by its randomly asymmetric wingtip arrangements.

Airbus A320's outermost cockpit windows are square save for a top corner being 'cut off'. Boeing 737's outermost cockpit windows are flat at the top and slope down at the bottom.

Also some 737-300s and 500s have them too.

I believe that the "winglets" at the end of the A32x series aircraft are actually called "fences". However, the A320 NEO aircraft actually have a blended winglet more like the A330/340 and Boeing 737 NG aircraft.
There are quite a few 737-700s flying that don't have the winglets, as (as Tengsted mentioned earlier) the revised airframe wasn't offered with them to begin with.
The 737-400 was the first of the 737 range to include an over-rotation bumper which can be seen on the rear fusleage under the APU. The 737-800 and -900 also share this tail skid.

The winglets can be offered as a retrofit on older 700s so, unless it's a completely separate retro-fit product, I have to assume that it isn't a part of the wing structure, otherwise the older 737-700s would be having their complete wings replaced. Something I rather doubt would be economically viable to do.

Actually, I believe it's about reducing drag at the wingtips and increasing lift without extra wingspan, which might require airport changes. The modest fuel savings (3-5% ?) more than offset the slight increase in weight.

Well, there's the economic value of the winglets to the companies which developed them and those which manufacture them: if you make more, you can make more profit.
There's the advertising value for the airline in having more vertical surface on which they can apply their expensively-procured logos.
There's extra work for the MROs which have to repair them when they get pranged.
And there's entertainment value for the spotters who like to know which aircraft have got them, and which don't.
