I already have an iPhone and MBP and this is why I bought an iPad. The one is too small for my old eyes and the other is too big to be convenient for just relaxing without a heat block sitting on my lap.
Will you keep your iPad when you will get the iPhone 4G?
I think a lot of people miss the whole point of the ipad. I am tired of sitting in a chair working on a laptop or a desktop. The iPad is freedom!
Really, the iPad is perfect. Not to small...not to big.
The iphone is an amazing product. But it is too small for any real sitting around (or walking) and actually being productive.
With the iPad at work, I can walk around the room and enter comments, grades, attendance, etc. While checking email, keep tabs on other pages. This would be completely impractical with either a netbook or a iPhone. I showed it to my principal, and he is ordering at least one for himself, but i suspect all of the admins will conduct their walk throughs on their ipads.
At home, I can be sitting in a chair, phone ring, get up, easily leave the room, with my pad so as not to disturb my wife sitting in the room with me. When I sit there with my laptop, it is this huge wight in my lap teachered to the wall. And, I admit, I go to bed with my pad. The wife usually is ready to go to bed before me. Last night I really needed to do something on a laptop (FTP access to some files)...and my wife was like, "do i need to sleep downstairs" as the computer was much brighter and noiser.
I know this is trivial to some, but as much as my life revolves around computers, it is important to me to have flexibility and freedom to move around. And as i have been saying to lots of people, if the iPad were only a larger touch, we would all still be using 14" monitors..or for that matter...the 9" screen of the Mac plus, etc.
