>>But, to extend the analogy, does that mean you will continue to use an electric drill to make the hole when a superior laser-based solution is available :-}

FWIW, healthcare changes just as quickly as IT. One big difference is that change doesn't happen for its own sake or because dominant vendors perceive that change will benefit them. If a laser drill does come along, the vendor needs to prove that it delivers a better result. Not requiring this leads to disasters especially when vendors make decisions to benefit themselves (which is why the FDA came about in the first place) and while the effects in IT may not be as profound, the behaviors and principles are still there. Proof does not mean advertising or blogs by incentivized appointees, it means proper studies to show that the cost and other effects of change are justified by the better outcomes or lower costs or whatever.

Another difference is that change doesn't mean delivering similar outcomes by wildly different means: it means new and better outcomes... cures, implants that last years longer etc etc. You won't see an eye surgeon boasting that after 100,000 Lasix treatments delivering excellent results for patients, s/he is now using Grusix that is wildly different and doesn't deliver a better result as far as the surgeon can tell, especially while s/he is so inexperienced with it, but the surgeon was feeling a bit bored with Lasix and the Grusix vendor advertises successfully and unless you change with the times, you miss out.

Finally, seems to me that MS has practically sidelined itself from the most important real customer-driven "change" in IT: the transfer of affection from the PC to the mobile device. To argue about what MS tool to use seems to me like arguing the benefits of buggy whip handles after Henry Ford has opened shop. Yeah, I know there will still be a place for grandpa boxes and you can sort of use NET for Android and iOS, but watch what happens as those vendors introduce amazing changes that are only available natively. Already happening. And in the last week I've been experimenting with a ZP100 that makes it easy enough to handle ordinary computing needs on a phone-sized device. The only remaining hurdle is the screen size, but both vendors are onto that too.
