But, the market I develop for doesn't care about that. They need to use keyboards, local workstations, databases, etc.

Sure. Some things will always need a big screen and fast data entry. In 2007, the way to offer that is certainly via a local workstation. But things change. The person sitting at that workstation also has a cellphone and uses it for functions that required a keyboard a year ago. She uses her txt service to check eBay prices and make bids. She pays bills. She sends personal e-mails she doesn't want to send across the office network. IMHO that shift is going to accelerate. If she gains the ability to use a bluetooth keyboard and screen from her personal device, she'll start wondering why it makes sense to fight the traffic to come to work and sit at a desk to use a device that was in her pocket the whole time. The trend has already started: in healthcare, most institutions are considering or have already enabled clerical staff to work from home using a variety of devices. Evidence strongly suggests that productivity rises when you do this. So where is the downside?

Eventually technology will allow people to abandon the keyboard altogether. IMHO the crash of a billion discarded keyboards hitting the dust will be audible half-way across the galaxy. ;-)

Hey, of course I accept what you're saying- you have to deliver to what's available today, not Flash-Gordon hopes for what may come tomorrow. I guess I'm just proposing an alternative that has less to do with vendor channeling of developer concerns. There's lots of other cool stuff going on out there and the early bird catches the worm.
