Summary: New Review 11/5/2014 The wireless card built in is a piece of crap. Computer lags and has trouble showing a powerpoint presentation on a screen. Purchased for sole purpose of showing powerpoint slides as clients enter business. Bottom line - it works, but could be alot better. Many days, when changing out slides, I want to throw it out the window because of performance issues!! Old Review 3/2014 Used for a flat screen tv and it works great!
