But you don't necessarily need HWR in order for digital ink to be useful. Eg, the Pocket PC has the option to store notes in "raw" digital ink, where it just stores (and later shows) literally what you write on the screen. Extremely useful for making quick notes, "doodles", etc. I use that a lot more than HWR. Similarly, the ability to be able to add hand-written annotations to displayed documents would be extremely useful, HWR or no.
