Many of these new tablets are decent, but both methods render something less than the perfect tablet.
These tablets (http://gizmodo.com/5459308/slate-showdown-ipad-vs-hp-slate-vs-joojoo-vs-android-tablets--more-updated?skyline=true&s=i)—not the convertible laptops of the past decade, but real single-pane slate-like ones—are in various stages of development, and have various operating systems. You have your iPad, JooJoo, a bunch of Android tablets, HP's slate, the as-yet-unseen Chrome OS (http://gizmodo.com/tag/chromeos/) tablets, the equally mysterious Courier, and the Microsoft-partner tablets that currently run a reasonably full version of Windows 7. You can easily categorize nearly all of these into two basic design philosophies: The iPad and Android tablets come from platforms originally designed with smartphones in mind; the Windows 7 tablets fully embrace the traditional desktop-metaphor OS; the Chrome OS and JooJoo strip out most of the desktop, leaving—perhaps awkwardly—just the browser.
But what about the Courier? If there is such a thing as a "third" option, it's what Microsoft dreamed up over the last year. Microsoft, already has its fingers in both ends of the pie, but Courier represents a truly different envisioning. Could the tablet that we've really been waiting for come from Redmond? Maybe, but at the moment the fate of Courier isn't clear at all.Making Phones BiggerFirst you have the method of taking a phone interface and making it bigger. That's the iPad, the Android tablets and, in some modes, Lenovo's Ideapad U1. Android tablets are basically doing an upscaling of the base Android interface, whereas the iPad also makes customized first-party apps to take advantage of the increased screen space. Both can theoretically run all the apps their little brothers can. Lenovo is also doing something very similar by creating a completely customized ground-up OS that's sorta widget-based, which is basically a smartphone in everything but name. (When docked, the U1 tablet becomes a screen for a Windows computer, but that's another story.)
So far, going up from a phone OS seems to be the better bet, compared to simplifying a desktop-style OS. But the phone experience is far from perfect.
When you work off of a smartphone base, you theoretically already have the touch interface locked in, because Android, iPhone, Palm and other smartphones now eschew the skinny stylus for your fat finger. It's a more natural pointing device for a tablet, since you can hold the device in one hand while pointing at it with the other. If you were to use a stylus, you'd have to grip the tablet with your forearm, like a watermelon or a baby, in order to provide a stable enough surface to press down upon with a pen.
Also, because you're working with a phone-up methodology, you get to sell a tablet relatively cheap by using high-end phone parts rather than low-end netbook parts. For example, you have Android tablets that are made from ARM processors (http://gizmodo.com/5358355/archos-5-internet-tablet-hands-on-android-power-but-wheres-the-flash) and Nvidia Tegra (http://gizmodo.com/5443299/hands-on-with-compals-tegra-2-android-tablet) graphics, which are basically meant to run high-end phones. Then there's the Apple A4 (http://gizmodo.com/5458314/apple-ipad-first-device-to-use-apple-a4-processor) processor, which is also ARM-based.
So for these manufacturers, they already have the type of modularized applications with minimal multitasking (in Apple's case, basically none) that can run decently well on low-powered hardware. Plus, this type of system requirements basically guarantees that you'll have a better battery life than the alternative.
Jesus already sung much of the praises of this approach when he correctly surmised that the iPad would have this style of operating system. But what about the negatives?
(http://cache.gawker.com/assets/images/4/2010/02/500x_itunes.jpg) (http://cache.gawker.com/assets/images/4/2010/02/itunes.jpg)If you're building a tablet from a phone OS, you would fail to have a completely stand-alone device, in the sense that a laptop is completely standalone. You couldn't have file access to dump photos, video and other media onto, you'd have to sync it to something else once in a while to get everything you need. And you have to go through a marketplace instead of installing stuff like a computer.
There is also no real way for apps to interact with each other. There's copy and paste on smartphones, and certain apps can read data files from certain other apps (like the contact list), but there's no way to interact like dragging and dropping files across applications. In the iPhone, you can't even multitask to work on two things simultaneously. You can on Android, but there's minimal interaction between applications. That's not saying it can't be done, it's just not so entrenched in the base OS or the base philosophy that application developers don't do it very often. If the OS maker doesn't do it, developers won't either.
Also, because phones are a very isolated experience, App Stores make it much easier to find apps that are both customized for your device and safe to install. This is great for phones, since stability is important, but when you're getting into higher-performance devices, you want the ability to choose what apps you want, not just pick from the ones that Apple or Google deem OK for you to consume. And since this kind of tablet is adapted from the phone ecosystem, that's the only choice you have.
