Eduardo puts it well, as usual :-) A couple of additional observations: > -----Original Message----- > From: public-bpwg-request@w3.org [mailto:public-bpwg-request@w3.org] On > Behalf Of Eduardo Casais > Sent: 05 March 2009 21:15 > To: public-bpwg@w3.org > Subject: Re: FYI - "Mobile Web 2009 = Desktop Web 1998" > > > Nielsen's article is solid.

Is it true that the following characteristics are converging, or are they in fact diverging? a) Bandwidth - could it be that techniques that apply to increasing bandwidth of OTA connections also apply to fixed connections? What are the relative gains when applied in those scenarios? b) Processing power and power consumption. c) Memory and Storage. > Convergence also > implies a unification of the context of utilization of the various > devices and > applications, and of user interface attributes -- a doubtful > assumption. > > 2) The "one Web" cannot hide the fact that developing different > variants of the > same application is unavoidable. A simple look at various W3C To my mind there is the "Hard One Web" which states that there is One True Experience, and there is the "Soft One Web" which says that bookmarks interwork between contexts, but that the experience differs between contexts. Of course there is also the "No One Web" position too. > guidelines (e.g. > for accessibility) proves the point: such documents are largely long > lists of > (justified) exhortations to provide a variety of alternative > representations: > for blind users, for deaf users, for browsers supporting frames or not, > for > browsers with or without plugins, for devices with or without pointing > devices > or keyboards or touch input, for monochrome or colour displays, etc. In > practice, > this "one Web" is implemented as disparate syntactic sugar to bind > together > more or less widely different variants of the same application -- this > is really > what for instance alt="...", <noscript>, <noframes>, media="...", and > @media > are for. > 3) Nielsen's article is based on rigorous studies of actual Web sites > carried > out with a range of mainstream devices, ranging from features phones > through > smartphones to the iPhone, and that are actually deployed -- not with > two-years > away promises from roadmaps.

I think the evolution of the desktop Web and indeed of the means by which it is constructed is often overlooked when discussing mobile evolution. There is something Newtonian at work, like "The Third Law of Motion" - for every convergence there is an equal and opposite divergence. (Sorry, Sir Isaac). It might be interesting to do a historical comparison of the form "The mobile Web is where the desktop Web was x years ago" and plot it over time. To be fair to the dynamics you'd also have to capture "The desktop Web is now n times what it was x years ago". > > All things considered, the equivalence "Mobile Web 2009 = Desktop Web > 1998" does not seem entirely far-fetched to me.
