Yes, I have used tablets quite a bit since 2002. I have a motion tablet (slate), a ruggedized slate, a Panasonic Toughbook tablet (convertible), a handful of UMPC, kneeboards, PDAs that run a variety of linux, winCE, and other mobile/semi-mobile OSs.
I also have a variety of pen based machines (IBM TransNote, Seiko Smartpad, etc) and a couple touch input devices (DiamondTouch, etc) that are prior to 2002.
It has been my experience (and observation of others) that tablet usage is indeed quite different than desktop or laptop usage. The example given above misses the defining characteristics of usage scenarios. The scenario should not begin with "the user initiates web surfing by opening the web browser". Instead, it begins with "user sits down on couch and picks up tablet while waiting for family to join him for a movie.". Or, "user spoons cereal into mouth while using other hand to interact with tablet resting on breakfast table."
You can include user context such as sitting on a couch or using the device one handed (heh) but not the "pick up tablet" part without artificially constraining your implementation possibilities. This is typically not desireable during design phase where use scenarios are employed.
If you have a defining characteristic of usage scenarios then perhaps you should state:
1) The context of your use of the term (RUP, Agile, something else)
2) The actual defining characteristics.
Simply saying that netbooks don't meet the usage scenario because you used the term TABLET in the usage scenario isn't useful in trying to persuade that the two cannot meet the same use cases and compete in the same market space.
Tablet interaction CAN be different from traditional computing. Certainly OneNote isn't very usable with a mouse. On the other hand it is hard to argue that WinXP or Win7 Tablet PC Edition is very well optimized for either pen or multitouch UI interaction given they are WIMP based. In fact, the cynical would point out they aren't much more than normal windows with a couple extra apps and some UI support stuck in there.
The tablet form dictates to a great degree, when and how people use tablet computers.
No, the tablet form dictates some of the limitations for the OS and UI designer. The UI itself constrains how users interact with tablet computers. A Win7 or Linux iPad is going to be significantly different in interaction paradigm than with the Apple OSX iPad.
The GUI helps define typical usage scenarios, but the form (screen size, input hardware, etc) also has a massive impact on actual usage.
Yes. But that doesn't say that two different products that meets the same need aren't in the same category.
It is the form, that defines the iPad and appropriate comparison devices. There is a massive difference in usage between tablets and traditional computers. Tablets and netbooks are so different that fixating on comparisons between the two is just baffling.
Then simply descibe how the Blackberry does not differ in the same way from the iPhone that the netbook differs from the iPad.
Blackberry, Netbook = physical keyboard, no touchscreen, traditional UI
iPhone, iPad = virtual keyboard, touchscreen, touch based UI
Blackberry and iPhone = about the same size, cost and general capabilities
Netbook and iPad = about the same size, cost and general capabilities
It has been my observation that nearly everyone who has actually used tablets for an appreciable period of time has come to the same conclusion.
You mean that they are suboptimal except as convertibles? More or less. Pray tell how many tablets you have used and for how long?
They are no more a substitue for netbooks (laptops) than are pocket computers.
Other than the tablet netbooks and a few UMPCs few are considered netbook substitutes as much as notebook substitutes.
This is ignoring the scads of tablets that appeared at CES this year which only really recently appeared and still remains to be seen how they pan out. I'm thinking not so great for things like the HP Slate based on my slate experiences.
Sure, iPhone users may use email less on their home computer. But iphones rightfully weren't defined as "going after the laptop or desktop market." The same will be true of the iPad. Or at least not in it's first incarnation.
Which is why I was very clear in pointing out that the netbook market has two segments and that Apple was targetting the higher end segment that buys netbooks as secondary computing devices. A point you clearly avoided...
