At the end of the day, what we have with the Toshiba Satellite L555D-S7930 isn't a multimedia machine. It is not a high-powered workstation and it's not a gaming rig. What the Toshiba Satellite L555D-S7930 is, is a cheap and moderately capable general use computer with a big screen.
If what you are looking for is a machine with a large keyboard and a big screen to make you more productive in the home or office setting for surfing the web or doing word processing, the Toshiba Satellite L555D-S7930 is more than capable.
The video stuttering issue is a letdown; many will expect this notebook to stream some video at one time or another. At this price, you simply won't get a powerful GPU that is muscular enough to decode HD video. The notebook user who cares nothing for media and simply wants a budget notebook to work on with a big screen is the target market for the Toshiba Satellite L555D-S7930 and will be well served.
