I can't comment on the Renoir but when the LG Secret (KF750) first came out I was like WOWOWOW, must get one! So, I got one - WOWOWOW, I wish I hadn't. Previously I've had Ericsson, Sony, Nokia, Sony Ericsson and Samsung, this is my first LG - Very disappointed.
Good physical build quality - Got a good weighty feel to it. The Secret has 4 touch screen buttons which appear to be little blue dots and then "ripple" when you press them - well they're meant to; that stopped working about 2 weeks after I got it :/
Now recently the touchscreen "button" to go RIGHT is dead.
Definitely won't be getting an LG phone again......
Hopefully the Renoir will be a completely different story though
