It's a Tablet Running a Touch OS
At the heart, er surface, the iPad is a tablet computer. This has been tried before and usually met with very little success. The problems were three fold: hardware, form factor and UI.
What sets the iPad apart from those that came before it is that it finally has the right combination of all three. The hardware is powerful enough to run the OS quickly while maintaining good battery life, the form factor is thin and light enough to be portable and the UI is tailored to the device.
The latter is especially important. Where Microsoft has failed in the past with both its approach to smartphones and tablets is in its attempt to scale down a desktop OS. As we've seen countless times, the only way to design for a different segment is to start from the ground up. Microsoft itself learned this with the Media Center Edition UI on top of Windows.
Since this isn't the 1980s, the iPad only has four physical buttons on the device. At the top you have a power/lock button, on the right you have a rotation lock switch (keeps the desktop from rotating) and volume rocker, and then at the lower part of the face of the unit there's a home button. If this seems familiar it's because this is the exact hardware layout of the iPhone, just on a larger scale.
The vast majority of your interface to the iPad takes place via it's 9.7" capacitive touchscreen display.
Along the bottom edge of the iPad you'll find Apple's standard 30-pin dock connector. You can use existing iPod Touch/iPhone USB cables, however this is a much more power hungry device and thus you can't charge off of a standard USB port (more on this later).
For your charging needs Apple supplies a single 10W power adapter, which looks a lot like the power adapters for the first iPhones.

I also thought the Moorestown recommendation was odd, especially when the next page was about the phenomenal battery life. If he made a more detailed case for it perhaps he'd have a point, but the simple "because it's faster" stance is lacking.Anand Lal Shimpi - Thursday, April 8, 2010 - link
Initial power specs for Moorestown appear to be fairly competitive with ARM based SoCs. Remember this is Moorestown, and not Pineview. The two chips are very different.Realistically I don't think it would be Moorestown, but the 32nm follow-on starts to make a lot of sense.
Take care,
Anand

Just curious, what are the initial power numbers for Moorestown anyway? Keep in mind that with the change in bus architecture and the use of LP DRAM, performance will be significantly slower in some cases than current netbooks. Also, would it really compare to an A9-class SoC?IntelUser2000 - Friday, April 9, 2010 - link
I have a feeling Apple didn't go Moorestown for two primary reasons.1) Timeframe
2) Cost
Moorestown should be announced shortly, but the devices based on it won't be available until Q3 of this year. That's 6+ months from when the iPad is going to release. And although Intel might achieve both better performance and comparable power usage, but the sacrifice there will be higher cost. Fully integrated SoC like the A4 costs significantly less.
Performance should be quite good. There's a 600MHz version for smartphones that can use Burst Mode to 1.2GHz, and a MID oriented version that probably clocks at 1.3GHz base and does 1.9GHz burst. It's supposed to feature "Bus Turbo" as well.
If they also do a full integrated memory controller unlike Pineview we have a good chance it'll be clock per clock faster than Netbook Atoms. Earlier on Intel claimed "30%" boost over previous platform but clock speeds weren't mentioned.

Moorestown will be a fully interated SoC. It'll have LP DDR1 and LP DDR2 memory controllers as well as a GPU, the Atom CPU and various peripheral connectivity. It's comparable to the A4 in terms of features although I really would not write it off as "comparable" in terms of power until some data is published.ekul - Thursday, April 8, 2010 - link
I'd agree the successor to moorestown is more promising. Are there even any shipping products based on moorestown yet? I don't think apple is going to take a gamble on an untested platform.I'm genuinely looking forward to seeing performance numbers for cortex a9, especially since there will be real dual core mobile variants, not just hyperthreading. A technique like what MS is planning for IE9, rendering a website on one core and compiling javascript on another, would help bridge the perormance gap along with the higher clocks.

really this is easier then a laptop/notebook?A notebook by its vary nature I can rest on my lap or a table and adjust its screen. To watch a movie I dont have to hold the thing up.
To type, I dont have to bend to werid angles to hold the device up, etc etc.
IMHO, it seems like alot of the experance is attributed to the newness of the device vs its actual usage. I'm wonder how this newness will wear.

Can't you do all of those aforementioned things on an ipod touch/iphone? There are already home automation apps for the iphone right now.What can the iPad do that the iphone/ipod touch can't? Beside having a bigger screen and longer battery life?
And for such a big device, the performance should be closer to an atom instead of a snapdragon.
If something doesn't fit in my pocket, then I would rather bring a light-weight CULV laptop with me... with touchscreen if one wishes (i.e. Acer Timeline 1820T) or a hybrid notebook-tablet (Lenovo IdeaPad U1).

"there are some things the iPad does much better than anything you might own today. Web browsing, photo viewing, reading email, any passive usage scenarios where you're primarily clicking on things and getting feedback, the iPad excels at."What exactly makes it better at those tasks? It's not that I disagree but, in my opinion, you didn't drive this point home. I don't understand why you think it's better. And yes, I read the whole article.

I don't think anything anyone can write can convince you. Many aspects just feel more natural to use. That isn't to say it's perfect everywhere but I think that as a casual mobile consumption device it's much better than a notebook, and much better than a netbook.
