So I’ve been using the Nexus One for just over a month now, and I’d thought I’d write down some quick thoughts about what I think of the device so far.

As far as the device itself goes, I’m extremely satisfied with it. The Android user interface is snappy on the Nexus One and the operating system itself is a huge improvement over Windows Mobile 6.5. But let’s not turn this into a review of the phone — that’s not really what I’ve been thinking about in terms of the Nexus One.

Last night I was reading an article posted on Wired about Google’s potential lessons learned from the Nexus One, and it made me think: OK, Google’s got this out the door, but what’s next?

And I guess that’s the point — I don’t think Google even really knows what’s next at this point. But there’s a few points of my own that I’d like include that Wired neglected to mention.

One thing that never ceases to amaze me though, is the speed at which wireless technology is coming at us. Google aimed quite high with the Nexus One, and the phone’s got some pretty killer hardware specs. But of course, the mainstream wireless providers have already come out with bigger and better hardware (like HTC Droid Incredible and HTC Evo). I think Google could have pushed the envelope a bit further with the Nexus One in terms of hardware, with a few simple upgrades like a forward-facing camera or more megapixels in the main camera.

I don’t care much about either feature — but it’s these small things that differentiate you from your competition. Otherwise, smartphones are pretty much all the same (and even all mobile operating systems are starting to look the same, especially with BlackBerry OS 6.0 around the corner).

So maybe I’m being a little hard on Google since I’m comparing phones that didn’t exist yet when the Nexus One launched to Google’s phone. But that’s my point, Google knew they’d be upstaged with new hardware — so setting the bar higher would’ve at least delayed the inevitable a little longer.

But once you’ve got that harder in the phone, then what? Well, to elaborate on Wired‘s second point, marketing really does matter. And not just some cheesy ad with people smiling and using your product, explain to me why your product is better (and in many ways, it is a great product, but no one knows unless you tell them).

And finally, my only really big complaint about the Nexus One — a lack of real corporate email support. To get all the security features and functionality you would expect from corporate email, you need to download TouchDown (a fantastic product by the way) for about twenty bucks.

Hey Google, ever think of just buying TouchDown and integrating it into Android?
