Great idea for small stuff, but for large items we're a long way from that.
Hi mate, I've quickly put the video files onto this 16GB Thumbdrive I bought for $13, plug it into your device and copy the files off.
Uploading 16GB to Dropbox is just not practical yet due to price and speed.
One day perhaps, but not yet and we don't live in "one day" we're living in Today.
True enough, but on the other hand, I've often found myself wanting to give someone a file, and there wasn't any thumbdrives lying around, and it was late so the stores were closed, or was otherwise too inconvenient to run to a store to get one. I'm just saying there are pros and cons to both methods.
And while transfering 16GB at once through Dropbox isn't feasible yet, it's good enough for plenty of things. If I'm giving someone 16 GB of files, I'd probably just copy them from my computer to a thumbdrive or DVD, and not involve my iPad at all. For quickly moving a file from my iPad to give someone, there are plenty of ways to do that that works today.
Perhaps Apple can just sit back, go nothing and think they are safe.
Then again, perhaps they need to consider offering consumers something more. Perhaps an iPad that CAN run OSX as well as just iOS ?
I don't expect Apple to sit back and do nothing, but I doubt they are going to make iPads run OS X. Actually, to be technical, iPads do run OS X, as iOS is just a modified version of OS X optimized to run on iPads/iPhones. But anyway, I know you are talking about getting full desktop programs to run on tablets, rather than technical details about what constitutes OS X.
And the fact is, Microsoft spend a decade trying to sell tablet computers that ran on desktop versions of Windows with slight modifications for tablet UI, and it never caught on. Because they were so hard to use. I think despite what Microsoft claims about Windows 8 tablets being able to run full Windows, Metro apps are going to end up being to desktop Windows apps what iOS apps are to Mac apps. That is, they will be so different from their desktop versions, they might as well be separate apps that use a common file format to read/write their data.
Yes, you could, in a pinch, run desktop programs on some (not all -- from what I understand, ARM tablets will be Metro only) Windows tablets, but the user experience for those programs would be horrible on a tablet.
In the meanwhile, Apple will keep improving on the features and user experience on their iOS pure tablet / phone operating system, and adding more and more compatibility and syncronization features with their desktop OS. OS X and iOS will be separate, but work together more and more seamlessly. Personally, I think Apple's way is going to work out better in the end, but of course, there's always the chance that Microsoft might surprise me. We'll see.
