Torrent, my favorite BitTorrent client, now offers a web UI. See if you can spot the differences between the Web UI and the Windows UI:
After spending about a year interacting with Torrent exclusively through Remote Desktop, I was pleasantly surprised to discover how good the web UI is. It aggressively exploits the latest Ajax techniques to replicate most of the rich GUI functionality of Torrent in a browser. But the web UI is still a pale shadow of the full-blown Windows UI. There are small but important details missing throughout, and part of the pleasure of using Torrent was luxuriating in its intense attention to detail, its wealth of well-designed data readouts. Using the web UI is like drinking watered-down beer. It doesn't satisfy.
But does it matter? Despite my nitpicking, I can do everything I need to do remotely through the web UI.
I do sometimes miss the fit and finish of the complete Windows UI. But if the only way to achieve full fidelity is to log in to the machine as a user via Remote Desktop, it's hardly worth the effort. Remote GUI technology has never caught on, either in Windows (RDP), in UNIX (X11), or even on the Mac (ARD). This approach has always felt like overkill, and it doesn't seem workable based on the historical evidence.
So the Web user interface is about 80% there, and even without new web browsers we can probably get 95% there. This is Good Enough for most people and it's certainly good enough for developers, who have voted to develop almost every significant new application as a web application.
I'm actually a little bit sad about this, myself. To me the Web is great but Web-based applications with their sucky, high-latency, inconsistent user interfaces are a huge step backwards in daily usability. I love my rich client applications and would go nuts if I had to use web versions of the applications I use daily: Visual Studio, CityDesk, Outlook, Corel PhotoPaint, QuickBooks. But that's what developers are going to give us. Nobody (by which, again, I mean "fewer than 10,000,000 people") wants to develop for the Windows API any more. Venture Capitalists won't invest in Windows applications because they're so afraid of competition from Microsoft. And most users don't seem to care about crappy Web UIs as much as I do.
None of this bodes well for Microsoft and the profits it enjoyed thanks to its API power. The new API is HTML, and the new winners in the application development marketplace will be the people who can make HTML sing.
Bruce Eckel read the same tea leaves as Joel Spolsky, and concludes that the future of rich web applications lies not in HTML, but in Flash:
- The typical user only touches a fraction of the functionality in most applications. Switching to an online spreadsheet like EditGrid or WikiCalc is hardly a catastrophic loss when you only used 1 percent of Excel's functionality to begin with.
- Online applications may be awkward, but they do one key thing that local applications can never do: embed snippets of live content in a web page. Instacalc may never be Excel, but so what? It's a completely different use case. Instacalc is ideal for embedding bite-sized, interactive nuggets of calculation next to a paragraph of text on a web page. It's the YouTube of spreadsheets.
Like Joel, I think the future of many-- but not all-- applications is in the browser. Web apps are good enough today for most tasks, and they're getting better every year. The web browser is the giant black hole of the computing universe, and like it or not, your application is caught in its immense gravitational pull along with the rest of us.
As useful and as clever as Torrent's web UI is, I'm still deeply disappointed. I'm disappointed that, with all the technology at our disposal, we can't come up with some way to deliver a full-fidelity user interface over the wire for an application as nifty as Torrent. I'll belatedly agree that web interfaces are "good enough"-- but after all these years of progress, why should we have to settle for something that's merely "good enough"? There has to be a better way out there somewhere.
