just not a huge jump in Specs for me...i wont even consider that phone. dont get me wrong, it looks nice, seems really fast, and i am sure it has a great camera. but TW looks like a kids toy, and any phone i have ever had i end up making it as close to a Nexus anyway (latest stock android version) so why not just use a Nexus?
on a side note, there are some great features to TW, so hopefully the DEVs can somehow get it on our Gnex's.
