iPad Review from an iPhone Developer- it's a legal pad for computing.

Now that I have the iPad for casual browsing, there's no danger of me getting sucked into work and I can focus more on reading, consuming media, etc.
I can also use the iPad in positions and ways I couldn't use my laptop in, like lying down on my side, standing (I like to pace), and on top of that I don't need to have my legs out in front of me to use it comfortably. I also find I'm not craning my neck as much as I do when using the laptop - it's started to relieve a lot of the RSS problems I have developed from using the laptop away from my ergonomically correct desk/chair.
The iPad is definitely a luxury item, but for people who are on the internet a lot, it's a small price to pay for the convenience. I liken it to having a second television at home, perhaps for your basement. Yeah, you could get by with only having one in your living room, but sometimes it's nice to be able to watch TV/Movies in your basement too, even if the screen is smaller and the sound system isn't quite as nice.
Motion, whatever happened to WriteTouch??
--Pecked out on my LE1600.
Granted my notes are typically more diagram-heavy and text-light, so having the few words and fragments tapped-out via the on-screen keyboard isn't a deal-killer. (I don't do long-form writing by hand, it's all typed and has been for years.)
Though I am still anxiously-awaiting an app that gives me a diagram/sketch-pad with place-able text-boxes, so I can have clear labels and in-context notes/annotation. Handwriting notes/labels on sketches is pretty inconvenient atm; having to zoom way in to write so the resulting text is legible but doesn't consume the image.
I also picked up one of the mind mapping apps but that doesn't really fit the bill because I can't draw diagrams in it.
So when I don't have a net connection to do direct entry I wind up using the plain notes app for text and just email things in.
For sketches and diagrams I've been using brushes mostly, though I'm trying out artstudio and it's pretty nice. (Ideas is nice, but no good for me, as it only exports in PDF)
At the moment, multiple apps and exporting is working for me; fits right into the old hacked-together custom workflow. I'd love a more appropriate and robust solution, I'm just enjoying such an improvement already that I decided to give the store a few months to mature before I start the app hunt.
As for the Sketch; I'm debating that one myself. How are you liking it? I wasn't sure what to make of the business-end of it from the pics (the drawing nub itself). Does it give the stylus more the mechanical feel of a pen or a brush?
Take that with a grain of salt though. I haven't done any kind of excessive testing with it for writing, just enough to see if I could get used to it if I found the right note-taking app. I think I could get used to it but I'd prefer the type I mentioned above.
To directly answer your question, I'd say it feels more like a brush than a pen.
