The iPhone is not very good for the average phone user as, for example, you can't easily text something with one hand, something that is an absolutely essential feature in Europe and Asia. iPhone is ultimately a luxury item aimed at technology enthusiasts, it's not a blueprint for how phones should be.
It's also rather stripped of features. Comparing the S60 User Interface with the iPhone User Interface is like comparing the controls of a jet and the controls of a car: there are significant overlaps, but S60 devices have far more features and options accessible to the user, so by definition they will be harder to use.
However, I agree there's lots of changes that ought to be made to the S60 interface if it's to be sold as a computing platform, and to some extent I wonder if it might be better (and I know this will sound like heresy) to make a brand new simpler-to-use computing-centred UI instead of altering S60.
When I reviewed the Nokia N800 internet tablet, I found its Maemo UI far, far easier to use and far more intuitive than S60, especially for computing and advanced communication tasks. Maemo was designed by the same company as S60, but by a different team within that company that started with a blank sheet of paper. Their fresh approach seemed very much more suited to pocket computing than S60, probably because they came to the task without any of the Series 40 baggage that the S60 team had to cope with.
I'm not saying abandon S60 as a platform, that would just splinter the market. What I'd suggest is putting an alternative simplified menu system on top of S60, which is what lots of third party applications already do.
Nokia has been done things like this before too, to some extent:
- The N95's optional "carousel" menu lets you access the most popular advanced features in a very easy way.
- The active standby screen on S60 3rd Edition onwards has made it far easier to deal with day to day issues such as appointments, missed calls etc, and gives fast single click access to popular applications.
- The alternative Horseshoe and V-shaped menu layouts on S60 3rd FP1 onwards, which don't help very much in practical terms but do at least show that S60 doesn't have to only use a row of static icons.
However, there's an important caveat to all this: we shouldn't get carried away by confusing the small smartphone market with the huge normal phone market.
The market for something like the iPhone (or the N95, or any smartphone) is only a tiny part of the entire phone world. The vast majority of people just want calls and texts, and you couldn't possibly say that something like the iPhone has made either of those any easier. The iPhone's lack of buttons and two-handed approach actually makes calls harder, and in pure phone terms the iPhone is a step backward.
The dilemma for phone giants like Nokia is that most people want phones that are phones, while the technology fans want phones that are pocket computers. Apple is happy catering just to tech fans, because that's their target audience, whereas phone giants have a much much bigger and more diverse customer base.
The problem for S60 is that, unlike the iPhone, S60 phones stradle both of these worlds, they're mainstream handsets and pocket computers. If they put something like the iPhone UI on their phones, it would hurt mainstream sales, but if they don't make any alterations they risk hurting their tech fan sales instead.
The only way to solve this is to make different models to cater for different audiences, with a computing-oriented UI for technology fans, and a more phone-oriented UI for the mainstream majority of the world. There's a precedent for this with Nokia's latest Series 40 handsets, the cheapest of which have a very simplified menu system while the more expensive models have menus closer in style to S60.
