Apple Sourcing Components for 17-Watt Power Supply, Speculation Focuses on Rumored 13-Inch iPad

Notice it doesn't go the other way though - the 5W adapter is not listed as compatible with the iPad, even though it can still charge it, albeit at a slower rate. Thanks for the correction on 12W adapter though.

If the iPad requires a 10W charger (G3 and later), it won't charge with a 5W charger.

It isn't listed as compatible because if it was, people would complain that it charges so slowly. But that's why you have standards - there is a USB standard for chargers, and any charger that conforms with the USB standard will charge any device that can be charged through USB. Eventually.

You guys talk it out

The correlation is between battery size and power draw. The secondary correlation is between screen size and battery size. Combine them and you have a correlation (though not as direct) between power draw and screen size.

The catch here is that the single most important predictor in general power requirements of all iOS devices is the screen (primarily size, secondarily resolution).

To say it makes "very little sense" is extremely ignorant, as, of all possible things to speculate on, it's the single most logical aspect of an iOS device to consider..

Ignorant is perhaps too strong a word. And perhaps 'very little sense' was too strong a statement. In either case, my point was that increase in the screen size doesn't seemlike the first logical speculation due to an increase in the power adaptor size, instead a larger battery/quicker charging time make more sense. A larger battery, obviously, would be in case of more power hungry components, one subset of which is screen size, the other being retina display.

If you have owned the retina ipad (I had the ipad3 and ipad2 both) you will know that the charger was barely sufficient to charge the retina ipad while being used. This sounds like a fix for more power hungry components.

So, to speculate about an increased screen size before all these other basic reasons 'makes very little sense.'

I think iPad 5 will be the same size as all previous generations but with thinner bezels and a larger screen. That might be a way to distinguish it with the mini.

Perhaps it's to charge the iWatch in the time it takes to shower?

Except, some of us are not "speculating".

It wlll, just very slowly.

If you use the iPad heavily while charging (3D games, or playing video over WiFi), the iPad might even eat up more than 5W, so it won't charge at all - but at least the battery won't get empty.

the twist is that the 13 inch iPad will run OS X.

Nope, the twist is that everybody who uses osX would like to have that, but Apple won't make it. OsX garden does not have high enough walls...

Anyway this revolutionary 17 W PSU maybe only means that next ipad has a bit better battery, that can live through applecare with over 50% capacity even with a bit faster charging.

Yes, and designers. And anyone who shows client work. The bigger the better in this case.

Panasonic actually has a 20" 4k tablet — which is 3840 x 2560 pixels. Now that would be a MaxiPad.

We are reaching the price-technology level, when "electronic paper" is starting to be option also for those who draw, not only those who read. Sadly nobody can ask Jobs anymore, does he draw with fingerpaints. Still camera is more important for photographers than tablet. You can "develop" your photos woithout touchscreen, but you can't take those photos without camera. Anyway, I'd guess that in 2010 Photoshop is mainly used with pen and touchscreen and old drawing tablets are disappearing.

Btw, wacom made 21" cintic in 2005, but it didn't revolutionize how people make visual content. IIRC, they also had one bigger and even more expensive at that time. Or maybe it never got through pre-production. This new Panny has similiar feeling; with 1/10th of it's price it would make a huge impact.
