How has Mobile Web 2.0 come to this;
One way that Web 2.0 companies can similarly adjust their services for mobile devices is by relying less on browser-based applications and more on small software clients that users can download onto their phones. “The browser will fade into the background,” said Wood.
The article’s not all bad though (in fairness, the main message is obvious – as Micah says, “Duh”). It also warns against “naive copying of PC services” (which I assume he means Web sites primarily targetted at PC users – a subtle but important distinction), which is good advice, but here’s a tip for mobile folks; if you find yourself moving outside the browser, or doing so while not using Web technologies (widgets), you’re not doing Web 2.0. It might be “Mobile 2.0”, but it’s not Web 2.0, and therefore not “Mobile Web 2.0”.
He used the example of Google Maps, an application initially designed for the PC. Because the application is built on Ajax, like many other Web 2.0 services, it pushes data out to the client device in order to speed up future user requests. On a mobile phone, that process drains battery life, eats up limited memory and results in potentially very high data-access charges. Google Inc. has introduced a version of the program designed for mobile phones that eliminates some of that overhead, improving the mobile user experience.
Well, guess what; using the phone drains the battery, consumes memory, and costs money. Mapping on a phone is going to use more resources than, say, doing email, which in turn will use more than checking the current time. But so what? Mapping is resource-intensive (although you could certainly do better than Google has).
Have you ever used the fat-client Google Maps Mobile referred to above? It’s not exactly the posterchild for efficient use of resources – I’ve got (well, RIM had 8-) the phone bill to prove it. I’m not saying the Web version doesn’t consume more, but I would be surprised if a little optimization couldn’t bring it in line with the midlet. Besides, I’d bet that if you asked Google the reasons they created it, resource consumption would be way down the list, and the lack of widely deployed AJAX stack on mobile devices would be at the top … which is rapidly changing, of course.
While the unique needs of mobility should always be acknowledged, and normally accomodated, remember that there lies a very slippery slope … the same one that WAP happily slid down years ago by internalizing the belief that mobile was so special that it needed non-interoperable mobile equivalents of every protocol from IP on up. And while there are, as always, exceptions – apps that are much better off as an installable app than a Web app – are you certain that yours is one, and do you realize what you’re sacrificing by going that route?
