What I'd really like Apple to to is to bring back some genuine 'wow' to their design and interface. That's a very tall order, but anything else is simply incremental upgrading. I've had my iPhone 4 since release day, and although I've loved using it over the past couple of years it is now looking pretty long in the tooth. The UI is no longer as smooth as it used to be, as it struggles with some apps that were clearly designed with a nod to the more powerful 4S. I didn't see the point in upgrading to the latter as I didn't see it as enough to make me jump.
So, what would I like to see?
- noticeable slimmer. I like slimmer - it feels and looks good. We're probably only a couple of mm away from what's awesome and what's too slim to use, but we still need to get there.
- a better, bigger screen. A couple of colleagues at work have the S3, and although it is too big for me personally, the screen is simply beautiful.
- NFC. Like many here I'm sure, I'm an Oyster user. I'd welcome being able to use the phone for this and many more payment options.
- A battery that gives reasonable use proportionate to the phone's capabilities. That is to say, don't make it capable of playing cool games and useful GPS apps if the phone dies by mid afternoon. Not everyone who goes out for a 5 hour bike ride with a GPS app wants to charge their phone immediately afterwards.
- on the above note, make the back cover a solar panel. Hardly anyone will put it face down and leave it idle, and it wouldn't charge that much but it would be cool. Apple's marketing team would have a field day with such a dramatic yet marginally effective idea.
- have some stock. Half the world's media hasn't yet seen through the reported 3 day queues in Oxford street, along with O2 in my home town selling out because they only had 5 phones in the first place, but I'm pretty sure I have. If you're confident in it, stock it.
- stop treating people like idiots. The whole 'you're holding it wrong' for the iPhone 4 was shoddy beyond belief.
- finally, Apple's new UQ is cool. Way cool. I'd like it to be able to fly.
iOS is fine
