I’ve always been a huge fan of desktop software. It allows developers to create a unique experience specifically tailored to a specific task. It promotes consistency within the OS, always knowing that the close window button is in the same location is a huge boon to usability. It’s generally faster and can work where your internet connection doesn’t. Last but not least, you have that copy on your hard drive that you can backup, put on a thumb drive or even print out as a hex dump if your so inclined.

Lately it seems though that, more and more of the software I use on a daily basis is heavily reliant on it’s client client connecting to the real back end over the internet. Email, instant messaging, Skype and web based documents are quickly being the primary conduit for my communication with clients. Add in the dizzying array of Twitter, Facebook, FriendFeed, YouTube, LinkedIn, Flickr and suddenly there are a lot of different ways to get a hold of me, none of which are dependent on my desktop software. The dark side of this cloud based interaction is that I don’t have a nice easy way to interact – a single touchpoint, like email, that I can be part of the conversation.

Enter Raindrop, it is an amazing new project from Mozilla Labs that promises to make email relevant again. In addition to email, it will bring in all of my conversation channels into one place, becoming a communication hub for me. This software is hugely exciting, taming the communication channels in a way that Tweetdeck and Seesmic Desktop can only dream of, while keeping all the information I gather in once central location. If this project ever launches and does only 1/2 of what it says it will do, it’s going to be awesome!

Today, TechCrunch posted an article about a new project called Inbox2. This project is web based and even has a Facebook application. It also promises to tame your communication environment! While the Raindrop application will definitely rock, it can’t touch the flexibility that the web version can reach. Raindrop is doomed because all of the data it’s taming is online, it only makes sense to build the application online as well.

This brings me to my original question, is desktop software dead? Google’s new Chrome OS is betting it is. In my experience, many software applications and iPhone apps are little more than a thin wrapper around a series of web services and API calls. Even when they’re not, like Pages or Word, I’m usually going to share it with a client via email, so why not write it in Google Docs to begin with? Obviously, the line is already blurring. As a developer, it seems easier to me to prototype an application in just about any web language and just simply run it in a browser window than it is to build a client for each device, iPhone, Mac, PC, Andriod, Linux you get the idea…

What do you think, is the end here for the Desktop Software market?
