Most digital cameras have excellent spot meters built in. To measure incident light, all you need is to measure a standard grey card that faces the main light source, so I don't see the point of using a hand-held meter at all, unless it's for some very special situations.
Besides, what does any of this have anything to do with panoramas?

It was built from 1961 to the late 70s. They used mercury cells
*because* they had no voltage regulator.
> Most digital cameras have excellent spot meters built in.You think? A good spot meter has down to 1° angle of incidence or even
lower. What camera features this? Ok, you can put on a telephoto lens
for measurement, but who will ever do that...
> Besides, what does any of this have anything to do with panoramas?Exposure is vital for any kind of photography, but it's even more
crucial for panoramas: How to balance between dark an bright parts?
Even if you shoot HDR: What should be the brightest and darkest
exposure? You are much faster decide this with a good spot lightmeter.
- Well, I want to chip in here,
I use both, I mean I use my lightmeter (Sekonic 608), the camera reading
in-camera but also look at the histogram in my live-view, as I swing the
camera from side to side.
What is handy with my lightmeter is that I can take 10 readings and average
them out. I definately don't think that lightmeters are obsolite yet. One
thing I think is more important, or equally as one can not do with some sort
of metering (be it manual or auto) is color meters, and again we can shoot a
grey card, 24-patch Macbeth chart et...
I would buy one if they were not so bl**dy expensive ;-)
anyway, just my $.02
PS: In camera 1Degree or less spot meter is archived with a very long lens
