Query: Buy this one for work.

I bought this notebook from Amazon at the end of February and was surprised to find that the McAfee software free trial had expired the month before. I was also surprised to find that Roxio was not installed as it is on the HP notebooks. After installing Norton Security, I found that everything worked well. Perhaps the best feature of the Toshiba Notebook is the ability to expand the memory to 4GB which may well be in this notebooks future.
