Rumoured Specs

Specs obviously don't tell the whole story, but that looks a very nice handset if those are true.

These never turn out as good as the rumors imply.

This sketch, which does look like the frame photographs that were leaked yesterday, claims to give the dimensions.

If it is real it looks like a 4.9" screen rather than 5.1" (125.1 mm diagonal = 4.93"). Funnily though the screen in the sketch has a 15:9 ratio rather than 16:9, which seems incongruous.

Ugh, seriously? That's even smaller than the S4. I thought this was supposed to be an upgrade. Not a downgrade.

Well, if it's real my bet is that is that marketing will round it up to 5"

Seriously, it's a matter of what you count as most important. If we assume the rumours are accurate it looks like being faster (duh!), thinner, metal-framed, with more internal storage (no more "< 10GB available out of the box"), as well as having an insane pixel density. Against which probably not a removable battery and, possibly, a slightly smaller screen. Personally I prefer the screen not too large, but that's me.
