If you got the Sony SAL-28 ... then the main differences are:

Wider maximum aperture
- the Sony SAL-28 has a maximum aperture of f/2.8
- the Sony SAL-1870 has a maximum aperture of f/3.5 @ 18mm

Higher quality
- fixed focal length lens tend to have better imaging quality (sharpness/contrast).

The Sony SAL-28 will produce a better image than the Sony SAL-1870.

Try it, use the 18-70mm zoom set at 28mm ... and then compare it with the 28mm.

Once you've shot a prime, you'll have a hard time going back to zooms.

Better image Quality, Faster lens. Apprieciate that Christmas present you got there.

(in general) Primes are better performers. Cost less, weigh less, don't get the "OMG you pervert" look or that "you must be a pro" look and just a gem to play with.
