I can't justify owning (any) iPad again, unless I get rid of my MBP. Having a laptop, an iPad, and an iPhone is just overkill in my opinion. They're all mobile devices, and one of them will inevitably be extraneous. The iPhone is super-portable, the MBP is super-powerful. The iPad is a compromise on both fronts, so it got sold.
That said, I'd buy an iPad if I ever ditched my MBP for an iMac. I could see it making a semi-suitable substitute in that case.
Understandable. But for me, all three serve very different purposes, and are not meant to replace one another. They compliment each other. And with iCloud even more so.
In my 5-member family household I have a 27" iMac, a 17" MBP, an iPad 2 (I can't really count that one; I'd have to pry it from my wife's cold, dead fingers), an iPad 1, 3 iPhone 4s (one was issued to me at work), and 2 older iPod Touch (camera-less).
The iMac is used as the Home base, iTunes, photo, movies, and docs repository, Apple TV driver, as well as the heavy lifter for things like blu ray conversion.
My MBP is my personal toy: virtual machines for every OS out there, iMac (limited) backup, school and travel machine, and music studio.
The iPad 1 is also used for school note-taking, Garageband, Fender Amplitude controller, casual games, email, tv, and chilling in the back yard while the kids bounce on their trampoline...
The iPhone is, well, a phone, camera, music player, nav system, email, and voice memo machine (I LOVE that app).
So, different purposes, all devices used to the max, by everyone in the family.
Perfect integration. The above is why for me, a move to Android is just unrealistic..
