The last statistic on phone screen sizes is the sweet spot is right around 4-4.5". Around 12% of people use phones larger then this size.
Another problem is fragmentation which makes it harder for developers to make multiple Apps for different sized phones.
You say you are waiting for Apple to do something great. Making multiple versions/screens is not great, just different.
Making hybrid laptop/tablet Apple is not going to do. All it would do is make a device that is neither a great laptop or a tablet. Touch on a laptop has always been sub par as well as a desktop experience on a tablet, not great as well.
Sweet spot? so apple's iphone is 4 inch and also it's not as wide.. Also it's not anywhere between 4.1 inch and 4.5.. it is dead on 4inch.. so I am not sure what the breakout between 4.1 and 4.5 but you get my point. We must be missing something.(12% + ( whatever the percentile between 4.1-4.5 ). Bottom line is money and apple is turning away from opportunity to make money.
And let's not even say apple only makes great stuff. Iphone 4s and iphone 5 was no great innovation. It was just lazy engineer at apple doing nada for 3 years. And their main selling point? Siri.. wow.. that's just terrible.
Apple keep saying fragmentation and yes apple ecosystem is much better than Android(I am happy about that). But if they think 4 inch is the best, why not make bigger device and have legacy app have letter box(do it based on 4 inch). I mean do something. I know there are many people who are dying to get bigger device.
So hybrid laptop is bad idea but you have seen stale osx upgrade for past 3 years. It's same crap and just incremental upgrade. This is apple's problem. It's stuck on past glory and do not think about changing something drastically. Today's world, this approach doesn't work. They are begging for other company to catch up and supplant them. Windows 8 is getting better and better and Android based desktop version is not far away. Google has wrapped us in all their apps'(btw, don't even get me started on apple's retarded way of not developing their own software to be best.. Safari.. lack of their own email system/software.. map.. universal messenger system) and it will be very easy for them to take over once fundamental infrastructure is there.(admit that this won't be so easy).
I am an apple fan. In my room, I have imac/mba/mb/iphone/ipod touch/apple tv/ipad.. But seriously, apple, kick that dude and start to work on something... geee
