Larger iPad?

There's a lot of rumours going around about a 7-8" iPad. So much so that I full expect one at the either the September event or the next iPad event. I can imagine the use cases so it and think it would be a beautiful, profitable, and (most importantly) a valuable addition to my current iOS setup.

However, i want something bigger than 7". Bigger than 9.7". What about a 22" 16:9 iPad? Not as portable of course, but the benefits in real estate, and the use case (one or 2 people, on the sofa, or docked on a desk as a workstation) make me salivate.

Ok, ok 22" might be a bit ridiculous for now, but what about 15" with the same ratio as the current iPad? Useable increase in screen size that won't scare people away, and I can see it being a big step up in functionality.

And why would anyone every buy a device like think if they already have a iPhone/smartphone +iPad/tablet +computer/laptop +another computer/laptop (we all have a few kicking about) +tv +set top box? Because people will want one. 2 years ago nobody had an iPad/tablet and I bet most people reading this will consider owning a tablet either 1 and mostly likely) necessary or 2) normal.

It's coming; we are all going to have an increasing number of devices, for use in different senarios, like an iCloud (or google, or amazon, or Microsoft) synced continous client. I would just love to see a larger iPad next year instead of in 4 years
