im latitude e4300 user here... been using it for years and battery started to acting up... not charging at all. browsing dell 5740 like the form factor and its price tag.

read a bunch of present owner faced issue on the WIFI thingy... and also found this at youtube - http://www.youtube.com/watch?v=bFHxia9Kwns

i think it's the back cover affecting the wifi signal. just wondering, has this been solved officially by Dell?
