Editing RAW photographs in Adobe Lightroom for iPad (in development), as well as making drawings and paintings using Adobe's new Mighty Pen (tiny nub, pressure/tilt sensitive Bluetooth 4.0 LE, built by Adonit) which is launching in the first half of 2014. I want to use my iPad to make artsomething that I couldn't do *well* on my iPad 2 so I gave up and stopped using it for anything beyond web browsing and some games. The iPad 2 had limited layers and canvas sizes. The 1GB devices don't do a whole lot better in this regard. I'm hoping that Adobe can squeeze Lightroom into 1GB of RAM, but considering that Apple will likely require apps to be compiled to 64-bits at some point (if they already aren't?), Lightroom will have to do everything within 700-800MB (20-30% less) on 64-bit. So at most, when you subtract out iOS 7 (300MB) Lightroom has 400MB effectively to work with. If the iPad Air had 2GB they would have 1.1GB after 30% and 300MB, or almost three times as much! I'm starting to get the feeling that Lightroom, which they initially showed off in May, hasn't had any more news come out because Adobe is waiting for the hardware to catch up. I want to use my iPad for content creation. That is clearly the direction it is headed. It just kills me that it's so close but hampered by lack of RAM.
For instance, while writing this thread on my iPhone 5 (1GB RAM) I switched to another tab to reference something, and when I came back everything I had written was gone as the page reloaded. Isn't that great? We clearly don't need more RAM for normal use. Clearly! Just accept the same RAM generation after generation. If 1GB is good enough for early 2012 then certainly it will be fine for summer 2014 when these are still being sold. Let's also keep 1GB for 2015 and 2016. Apps and websites aren't likely to ever become more demanding. Maybe we should just stick with 512MB like in the iPad 2, which is also being sold. I mean, that thing runs iOS 7 so well! I would just have to wait a few seconds between keystrokes for it to catch up on my iPad 2. Not a big deal or anything. Who doesn't love lag anyway? I loved it so much that I sold it on Craigslist without even having another tablet to replace it because it became practically useless to me. I even felt bad about selling it to the guy. But Apple does it every day!
I'm by no means saying that another tablet is better than the Air, I'm just saying that I think Apple is missing a real opportunity to take tablets to the next level with higher-end creative and productivity apps. Perhaps that's where the iPad Pro comes in, and perhaps I'm the customer they have in mind: A creative professional who wants powerful apps on the go and is willing to pay more for it. I just wish I had some assurance that such a product is actually coming. I think they could do it now, but are perhaps waiting to finish developing their own pro apps such as Aperture and Logic for iPad Pro. Or maybe a dumbed down Final Cut, though something like that would surely require at least a USB 3.0 port. Perhaps they're working on Thunderbolt for iOS? Just one Thunderbolt port to provide a world of possible expansion on the iPad Pro. Though that's probably pushing it this early in the game.
