I'm just wondering, would anyone want a flush home button? I just thought that a flush home button would aesthetically look nicer, have better tactile feedback and be easier to press than the concave home button? I've been through 8 iPhones and the variation of their tactileness has been different across all, some clicky some mushy and I just thought that a flush home button like the centre button on the clickwheel iPods would be so much better. Thoughts?
