i'm the opposite way. i see no use for a phone that folds in half. i like my phones to be usable one-handed, and having a clamshell shape that folds out into something i can't reach my thumb over is just dumb. but if i can have a normalish candybar phone that unfolds into a whole-ass tablet in my pocket? absolutely.
...but not for $2500. maybe for like... $1000. that's twice what i paid for my last phone.
