My colorimeter is waiting at home according to FedEx, and my spectrophotometer is shipping tomorrow, so I'll soon be doing my first calibration on Calman 5.
I know that I'm supposed to calibrate my colorimeter to my spectrophotometer, but will there be any other times that I use the spectrophotometer, or is it purely there for reference?
If you're just interested in measuring color (chromaticity coordinates), then a profiled colorimeter should serve your purpose well. Might be a good idea to profile your colorimeter before each major calibration (definitely if you switch displays), but other than the purposes of profiling, you shouldn't need the spectro, unless you want to examine the actual spectral power distribution of your display (which is a different form of information than color information).
Some of realities and reasons why you profile has been lost in translation.(pun intended)
In the world of absolutes and reference, you can only use a specto device, the caveat is to do it accurately you need a CS2000 or similar.
It was found in research that a Tristimulas Colormeter can produce as accurate results, but only if the CMF matched the model CMF that the spectro uses to convert the spectral data.
When the colormeter does not natively match, the correction profile produced by the differences between the reference and the colormeter can fix the vast majority of the problem, the caveat though is no correction is perfect. There is always error.
However, reality.
Most are not measuring for reference sake of absolutes, displays and course controls means that method and device error differences are not important enough to show up in real world differences.
However, the limited nature of consumer spectros means that some improvement can be made to a consumer colormeter for both speed and accuracy on most given display types.
Many still use just an i1pro or i1D3 or many other basic devices, some have a life span of usefulness some don't.
In the end, the Spectro will give you reasonble accuracy for a longer life span.
A colormeter will degrade, but has a speed advantage, where the profiling will adjust for the degradation as time passes, thus gaining the speed and spectro accuracy.
As new devices, you will probably not find a large difference between the devices.
The i1D3 is just a sealed colorimeter, right? For $229 it seems like a bargain. Does it have limited life span of usefulness like the i1D2 colorimeter that had exposed filters? My i1D2 LT is useless right now because it has drifted so much.
Now I can't decide if I should spend $1k on a i1Basic Pro 2 or $229 on a i1D3. Certainly not the latter if the i1D3 is going to have a very limited life span of usefulness...
Yes the D3 is a colorimeter with sealed optics. It will be more accurate and will last much longer than the D2/LT. A spectro will be more accurate on a wider range of display types than a colorimeter, and you can use your spectro to profile your D2/LT, so it's not completely useless.

You could also purchase a spectro such as the i1pro or colormunki photo/design and then use that to profile your i1d2, it will benefit from the corrections of the spectro and benefit from faster reads and higher accuracy at lower light levels. It's the route I chose to go. At first I tried shopping around on ebay for a used i1pro, but never had luck winning any auction at a reasonable price, so I just opted for a brand new Colormunki Photo off of Amazon.

Got one this week - i1 basic rev d, for 200 Gbp - had to be quick though, i1 pros regularly go for 275 - 300 here.
