I got the black edition so i maybe bias but the remote is pretty handy and maybe i won't used it to its full potential but maybe i will i still want to have those options.
$400 Black w/ Remote
$300 Silver + wifi remote $80 = $380 not unless you have and iphone you can use the app.
$100 for the extra features and wifi remote for me it's worth it.
About the battery there's really nothing we can do about it co'z they all sucked.
