I like that it's black, although yeah it hides the fact that it's metal.
I've ordered a cheapo 'pebble steel' band, also in black, but not sure if I want to fit it now after reading about the cracking...
On battery life I decided not to bother charging it last night and so after taking it off the charger at 8:34 last night, using it for a fairly normal day (maybe a bit light on texts/hangouts messages) and sleeping for 7 hours before getting up at ~6:30 today it's now on 49%. So for me at least it looks to have plenty for 1 day and probably enough to last till the end of today as well, but I am quite a light user.
