Google has two hurdles in getting into the office applications space for large enterprises. One is security, which it addressed yesterday by purchasing Postini for $625 million (how about a beer in the parking lot to celebrate?). The second is patience, as Google waits for businesses to catch up with the reality that the web is becoming the true platform for 21st century business. \nSince Google Apps operates on a Software as a Service (SaaS) model, it needs workers to be connected to the internet at all times. As this Wired posting from a few months ago points out, that fact, coupled with the absence of a PowerPoint equivalent, still puts Google Apps at a disadvantage. For instance, I could take my laptop onto a plane or write an e-mail in an offline mode for Outlook, but I couldn\u2019t open my Gmail.\nThe plane is an extreme example. But it hits on an interesting idea: though we talk about always \u201cbeing connected\u201d\u2014whether it\u2019s through our cell phones or PDAs, or from WiFi at the library, coffee shop or airport \u2013 it doesn\u2019t always truly feel that way. Telecoms, clamoring for supremacy to have the largest networks, end up having problems all the time, not matter how cool the gadget one uses to access their network is. I can still think of plenty of times where I can\u2019t get wireless internet on my computer or my phone\u2013 if the carrier I subscribe to doesn\u2019t have a signal, if the nearest network requires a password that I\u2019m not privy to. I won\u2019t even get into how slow the web browser can be if I\u2019m connecting through my cell phone network.\nGoogle is trying to do its part. It has already implemented WiFi in most of its home town of Mountain View, Calif., and it is proposing to do the same in San Francisco. Smaller communities have begun following suit across the US. While it seems to be helping the public good, perhaps it\u2019s a business plan: if everyone is on the web all the time, the SaaS model will win out over time.\n\nI, for one, hope they\u2019re right, because their software philosophy that you should minimize how much stuff you have to install is a sound one. Just from the perspective of a user, I\u2019ve ruined too many computers by downloading software unknowingly. And that\u2019s just my consumer laptop. \nAn enterprise\u2019s network -- that's a whole other story entirely.
