I've used it for spraying finishes and such and it really is nice to have something big.
That being said, I missed having something portable, so I did buy a little 99$ compressor. It works great for driving brads and nails when I want to use them away from the shop and don't want to have to run hundreds of feet of hose. It's also a great little tire pumperupper...
So, I guess my advice is go big, but you might just want to get a little portable one as well, but I'd stay away from anything in-between...
