I just don't see the content for these TVs.
Screen tech is allready so far ahead of content that most 1080p TVs don't show content made for it.
With 4K TVs this is just increasing so much that it isn't funny any more.
I hope that if Apple feels the need to make a 5'' iPhone that they keep the 4'' version too.
I don't understand the usefullness of a phablet.
For those with not so good eyesight there is allready a solution to that problem.
It's been in use for several 100years, tested and found to work.
Sorry but Apple isn't claiming that the iP4 can't do turn by turn. I have got an iP4 and turn by turn navigation works perfectly. When you install iOS6 the iP4 will do the trick. Don't know about the 3GS.
