But it IS personal. It's YOUR arrangement of pinned apps/live tiles displaying YOUR information! I'm being a little dramatic here, but if your phone is boring, your information is boring! That is why your WP7 will look different from anyone else's. People have preconceived notions as to what "customizable" means, apparently. Which isn't really surprising, but given how different WP7 is, a different approach to customizing should also be taken. And this isn't really directed at you personally, just the overall mentality of WP7 needs wallpapers, et al.
But its still personal preference your idea of what's boring is not necessarily someopne lese idea of boring. Both opinions and preferences are valid. My prime consideration is that my device works for me and helps me work smarter at work and keeps me informed about what I need to know and be doing. Antyhing else is gravy that I can take ort leave.
