Wild Guess: Mac OS X Lion will “run on” iPads with iOS5

So, 10.7 turns out to have true multiuser support — as in it turns your Mac into a time-shared system. And it has Mac OS X Server’s functionality built-in. And it has a bunch of convenient file-sharing functionality tailored to iOS users (iPad users in particular).

Hmm. What’s something that Apple does that none of the Android crowd (HTC, Samsung, LG, etc.) do that would provide huge synergy with iOS products? Apple makes Macs. (Note that while Google certainly knows a lot about servers, Google’s one major foray into the consumer OS market is the “browser as OS” — not something that will naturally extend to a time-shared home-server.)

Right now, the best remote-controlled media device in our house is a Mac Pro (with Netflix and Hulu). Why? Because we can use any iOS or Mac OS X device in the house to screen share it (VNC for non-Apple folks) and we never lose them (as of this moment, one of our two TiVo remotes is missing and we just found our Roku remote after losing track of it for nearly a year — and TiVo support among third-party remotes sucks, while Roku support is non-existent). There are many really nice screen-sharing clients for iOS, some special purpose (such as TouchPad) and others general-purpose (such as my current favorite, Remoter, currently on sale for $0.99 — and no I am not getting paid anything to link to either product).

Just yesterday I was trying to set a new profile picture in Facebook using my iPad in the living room and I realized that Facebook’s cropping UI isn’t usable on a touch-screen. So I logged onto the Mac upstairs and made the change from my iPad in a couple of minutes. It was a little clumsy — the Mac is running at 1920×1080 so there’s a fair bit of pinching involved, and I had to figure out how “click and drag” works on my screen sharing app (since it was the first time I’d needed it). But screen sharing onto a machine with a much larger display is always fiddly.

So, suppose this kind of thing gets built into iOS5 at a deeper level. Now, your iPad is, among its many virtues, a Mac OS X tablet running at native resolution. (But but but… scream the Linux/Android fans, we can VNC onto Ubuntu… yeah.)

Oh, out of curiosity, I wonder how well the new OSX gestures and UI elements work when used entirely by screen sharing from a touch-based device?

This also dovetails nicely with rumored improvements to MobileMe and making the “back to my mac” feature from MobileMe free. (Oh yeah, and I guess you can use Flash conveniently on your iPad if you really want to.)

But wait, there’s more!

What might a future device that supports iOS and Mac OS X device look like (or to put it another way, what does OS X look like when it becomes “legacy”)? Two different login shells on the same OS core. Now you can boot up your Macbook Touch (MacPad? TouchBook?) and launch into iOS by default. Or you can log into OSX by default. Either way, you can get to “the other side” either by “fast switching” or by “screen sharing”.

So in summary, perhaps what 10.7 is really about, from a UI perspective, isn’t copying iOS UI elements back to Mac OS X for its own sake so much as making 10.7 offer deep usability from touch-based devices so that you can enjoy OS X while logged into your Mac from your iPad 2.
