Following up my series of posts about using a keyboard with the iPhone, CNN contributor Amy Gahran says the iPhone keyboard arrived too late, as she’s already switched to Android. Her short article gives a few more reasons why a physical keyboard is a good idea for a phone, and even links to an Android bluetooth keyboard (that folds!).

And keeping with the iPhone/Android theme, Robert Scoble of Scobleizer writes a good summary of why he’s sticking with iPhone, unlike Louis Grey who just as compellingly advocates the Android platform.

Over at YouTube, you can now watch videos in 4K resolution … assuming you have one of the rare and super expensive 4K projectors. For those unfamiliar with 4K, imagine putting together 4 1080p televisions in a 2 by 2 grid, and you’re still not reaching the kind of resolution we’re dealing with. Viewing is only half of the problem, as 4K camcorders like the RED One are few and far between, not to mention beyond the budget of even many independent filmmakers. Of course, you won’t be able to take full advantage of this feature on even the largest computer screens currently available, but the notion of streaming ultra high definition video is a delicious taste of the future for tech nerds.

Then again, here’s a camera that will probably have the ability to record in 4K.  Canon has showcased a new “Wonder Camera” that promises to be the future of photography and video. Perhaps the most impressive and interesting part of it is the lens, which has an unheard of range of macro to 500mm. Not to mention its ability to capture up to 600 frames per second. The product is still concept, and Canon says we won’t see something like this on the market for another 2 decades.

I’ve been using the iPhone 4 and bluetooth keyboard as a mobile writing platform, or netbook of sorts, for a few days. I’ll talk more thoroughly about using the setup later this week, but for now I have to say that, for certain tasks, I absolutely love it. Pairing is effortless and the simplicity of tapping out a few hundred words when inspiration strikes is makes it a great alternative to booting up a laptop. Anyone with an iPhone who needs to crank out longer documents should go get one, now.

I’m writing and posting today’s update entirely from my iPhone. No, I’m not tapping on the touch screen, but comfortably typing on my shiny wireless keyboard.

In my excitement over the new 720p camera and iMovie for iPhone 4, I somehow overlooked a feature I had actually been hoping for since the first-gen iPhone; Bluetooth keyboard pairing. As both a writer and a college student, a super mobile writing setup has been near the top of my wish list for a long time.

Currently, I’m sitting at a coffee shop with the iPhone propped up on my wallet (who needs fancy stands?), headphones streaming Pandora, and the brushed aluminum keyboard resting gracefully, awaiting my utterly insightful keystrokes. Ok, it looks cool, but I admit it’s not a perfect setup. Especially since the screen angle isn’t very adjustable with my improvised stand. But I rarely need to look at the screen while typing, so it’s actually working quite well. And since there’s no virtual keyboard that pops up while the wireless keyboard is paired, more of the document is visible, taking advantage of the whole screen.

So, what’s the advantage of this setup over just a laptop? Well to be honest, not much. This is my first time using it, and the novelty factor is still in full effect — I’m sure I’ll still use my laptop in most circumstances. But the freedom of being able to write and post anywhere I want (well, anywhere with 3G) is, one has to admit, very cool. It also takes up a smaller footprint on small tables, such as classroom desks, and I’m looking forward to taking notes with this setup this Fall semester. And as someone who bikes just about everywhere, the bluetooth keyboard weighs next to nothing on my back compared to a laptop.

I’ve heard from half a dozen aficionados that since getting their iPads, they’ve used their laptops anywhere from half as much to 90% less. I can’t verify that they’re not exaggerating, but it does make sense. Most of what the average person does on a computer requires minimal processing power — web browsing and e-mails — and yet would be greatly improved by a better user interface — a touch screen.

And I admit to being wrong in my early assumption that very few people would purchase the iPad, and that it’s just an expensive toy. To me it still is, but after talking with iPad owners about the device and how it fits into their lives, I now at least get it.

But I’m far too cheap to buy an iPad.  So since I’m holding out on buying a tablet, I’m curious to see if I can do the same thing with the iPhone. Now that I can pair a physical keyboard, and with rumors of iWork coming soon for the device, it makes me wonder how much is possible within the bounds of this 3.5 inch screen.

For the next few days I’m going to replace as much of my computer use as possible with the iPhone and keyboard. This will be impossible at times, since I’m shooting a wedding tomorrow and will need to import the footage, but most of what I do on my computer is simple writing, web browsing, and checking e-mail. Whether I end up getting frustrated and giving up, or being pleasantly surprised, I’ll post updates here in the coming days with my thoughts on the practicality of the setup. So stay tuned these next few days, and while you’re at it, why not subscribe to the RSS feed? ;)
