Hi, I'm currently undecided between the Toshiba Satellite C55- A5386 & Lenovo Ideapad G500. They have a $100 difference, the Lenovo being the costly one. The Lenovo has an i5 processor but the toshiba has only i3. I'm only going to b using it for domestic Internet surfing & such. Is it necessary to spend a $100 extra for the Lenovo or would the Toshiba be sufficient? I currently own a compaq that sadly let me down when it came to battery life.
