Here is another article on the reuse war that is just getting started. My perspective from my little corner of the world is that it is very difficult to achieve business reusable services. Just as the article points out, getting the top down cross organizational business perspective is a very difficult task in the real world. Don't believe me, go try it.
Another thing the article said was around vendors forcing IT into SOA with their products. I'm not buying that. Shipping me a product that has its API's exposed as Web Services is not SOA which is what most vendors are doing. I do think vendors are putting a lot of pressure on IT to buy into the SOA concept buy trying to upsale their products. But still not SOA.
