I'd have to say the iPad 2. Mostly because of the addition of the camera, which is really just an incremental upgrade.
This is my question, as well - what IS next? 2011 is obviously the year of the tablet, but take a look at Apple's landscape in a general consumer POV. They have:
1. Desktops for my desk
2. Laptops for my backpack
3. iPads for my couch
4. iPhones for my pocket
5. AppleTV for my television
6. Airport Expresses for multi-room music
7. Time Machines and Airport Extremes for networking and network storage
I don't have any more places to put things! As of last year, everything else is in an incremental upgrade stage - the iPad is getting a camera, the laptops are getting ultra-thin (Macbook Airs), the iPhones are getting faster (4G), and so on and so forth.
My big question is simply, what is the next big device? I've replaced so many of my gadgets with software - for example, my iPhone now acts as my cell phone, my Garmin GPS, my MP3 player, my remote control (Sony Bluray remote, HTPC remote), my Gameboy, my point & shoot camera, my Flip pocket camera, my alarm clock, my voice recorder for notes - the list goes on and on.
I love hardware and gadgets make me happy, but I have a hard time seeing what the next widget will actually be. Computers have reached a point where they were pretty dang good between Windows 7 and Snow Leopard, when combined with a Core i7, an SSD, and 8 gigs of RAM (> $1000). I just set my dad up with a new Engineering rig that has 24 gigs of RAM ($190 shipped) and a 28" LCD monitor ($249). Technology is in an awesome state of affairs right now, but - what's next?
What's next? That's the question I want answered :hmm:
