Used this to replace an old celeron my TV that died last week.  I have bought a few of this style dell's for various purposes, this is the lowest end I have bought and it works great for its purpose (streaming and access to my media library).  I have not found any performance issues, unlike my old computer.However, the picture shows an internal wifi with an external antenna, that is not what I got, it did come with a tiny USB wireless dongle, so it does have wifi.  However, this tiny device was not adequate for my needs as this pc is somewhat remote from the AP and had poor reception.That said, I may still buy another one for my other TV, the price is right.But I wish they would note somewhere obvious that the pic showing the attached antenna implying an internal wifi, may not be what you get.  Although maybe there is an error in my order and I got the wrong one.
