For a long time now there have been web applications mirroring pretty much all the applications I use locally, email, calendar, spreadsheets, etc. I keep looking at these and feeling like I should jump on the bandwagon, after all lots of the people I work with use them and rave about them so they must be great right? The problem is I can’t figure out what I am actually missing, and most of the time I can spot immediately things I would miss by moving to them.

Obviously one clear benefit is that they are available anywhere in the world, you just need access to any computer with a modern web-browser. But you know what? Wherever I go in the world I take my laptop, or if I don’t it is because I really want to relax and be offline completely. About the only critical thing that I might need to get updates on is my mail, which I do have a webmail access to anyway.

The online services seem to fall down for me in a bunch of ways:

• I like to be able to run applications separately from my browser. I’ll grant you that tools like Prism make this sort of thing possible so that failure is going away slowly.
• No matter how good browsers become I don’t believe HTML will ever create as good a UI as a real application can. For the most part they are restricted to a single window interface, with pseudo windows hovering above looking nothing like platform native.
• They need you to be online (let’s ignore gears and stuff for the moment, I haven’t found the technology to be quite there enough yet). As I said I take my laptop everywhere. I can look at all my mail and calendar without needing to pay for an internet connection in some random hotspot.
• They simply don’t have the features that my local apps do. I expect this to change over the years but many of the online offerings are basic at best.
• How do I back up my data? Seriously, if I want to back up my gmail or google calendar what do I do? If I want to back up my local mail and calendar I just plug in a hard disk and let OSX deal with it. Obviously the opposite to this is that if my machine goes down then the online service will still be there and I’ll only have a potentially stale backup, but my backup is never more than a week old, and I can tell you I’ve lost more data over the years due to online systems going down than local machines breaking.

So here I am, wondering (again) what to do about task management. I keep feeling drawn to things like Remember The Milk because they are all online and Web2.0ish, but I’m not sure quite why. I’m sure I must be missing something critical about using the online apps, but I just can’t figure out what it is.
