I write software for a specific community yes but there are a lot of places like where I work and while we may have some web enabled stuff people will use their phones for there's not a lot of our development that anyone would want to do on a phone.
Our main 200 applications that are our core business mostly run in commandline batch mode on the super computer. And while I have made a small portable, wearable cluster of windows mobile phones and ran some stuff on it as a cluster just for demonstrating exactly how much you can do on these things way beyond what 99.9999% of people think they can do there are limits. My WM6.5 phone does spreadsheets and word and power point really well, even doing presentations and yes I have adapted it so I can actually program using my phone, and the wearable cluster is cool most people could not even try to get them doing these things, except excel and power point, and so expecting most people to be able to do real work beyond emails, reading, writing some light documentation or something like that is all they can do. You are not going to run your fortune 500 payroll on your phone (maybe mine, not yours) so when a story like this comes along and says get ready to do everything from your phones I have to laugh and try to figure out what portion of my definition of "everything" does their everything contain.
