If you could choose one feature for iPhone OS 4.0....

I think Apple are trying as hard as possible to strongarm Adobe out of Flash. They won't be successful in the short-term - Adobe and many websites are too embedded in the lure of Flash. In a couple of years, there will be few people who will require Flash to be on anything, but unfortunately, the technology, still proprietary, is stuck in our bloody world as strong as anything is.

Well, have a read through that interview with Jobs fom 1994.

Looking back now after 15+ years it shows that Jobs has a pretty good foresight. Sure, right now everyone is asking for flash, but forcing HTM5 might actually be better in the long run. And the iDevice has actually enough market power to push some decision makers in the right places into the right direction.

Something I'd like to see is the ability to suppress the icons for the default applications. I know you can shove them all to the end thanks to the "invisible" pages concept, but that's annoying and they still come back as you delete applications. If Apple doesn't want me to delete them off my device, fine. I can live with that. But I'd at least like to reclaim the valuable launchpad space their icons are taking up, seeing as the only ones I ever use are notes and photos.

Definitly multitasking! Yeah, you can be on a phone call and use one other app, or listen to music and use one other app, but there really is a need to run more than one app at a time. This will be even more of an issue once people get their hands on the iPad (runs the same OS as the iPhone). Copy and pasting from one app to another is good, but when you have to do multiple then the ability to quickly go from one app to the other several times would just make it so much better.

The other thing is Flash! Once Flash is available on all the droid devices, Apple will be left behind. It will be two years at best before HTML5 even comes close to replacing some of the basic uses that Flash is now used for, and it certainly won't replace it completely. With so much Flash content out there, Apple's devices are NOT the best way to surf (despite their claims).

I don't think multitasking is the answer -- at least not with the limited batteries we have. Quick loading services that launch in the background when needed or maybe some sort of flipping between active apps (where no processing is taking place when they aren't active on screen) may make more sense.

[RustySabre]

I think multitasking will be more of an issue on the iPad, but I think it has very limited usefulness on a small device like an iPhone. I struggle with managing all my open windows on a 19 inch monitor for my PC, I don't think I want to try that on my iPod Touch screen

Multitasking is a MUST at this point in time. The fact that we don't have the ability to run true background apps is appalling at this point in time. It doesn't help that I operate on an iPhone 2G and don't get PUSH so hopefully something like 4.0 could assist in multitasking?

I assume that it'd take a bit of a toll on batteries, sadly. Still, I'm willing to take that hit.

[cjrnic]

I agree about multitasking and better app organization.

[Darrel43]

How about something like this maybe?

That's looks amazing if you ask me, a great way to get from say, page 3 to page 8 in a flash. I also have many apps and its annoying flicking page after page.

[NineSwords]

Organisation is really bad. The 'dock' should be improved to work like in OSX - as it is now, it is just a tiny favourites bar. I wish for a toggle in each app to force-quit auto-rotation.

Wish granted.

I must say this really REALLY looks slick.

[shigzeo]

It does - sadly, the feature I may look forward to most is auto-rotation lock! Haha. Fortunately, the iPad looks to be cheap in Canada - only 549$ CAD (which had better fall against the Korean Won), so I might get a bit of that action first! See the homeland in July this year.
