need a laptop advice

[a rebours]

Hi all,
I am not a regular postr here but wondering if somebody can give me advice. My old laptop died recently, so I need a new one. I am thinking about Sony A790.

I tried searching this forum and all the posts seem to only discuss Dells and Inspirons. So is there any reason to prefer Dell to Sony for the purpose of mainly playing poker? This model should allow 4-tabling wothout overlap, and it's not as heavy as Dell, from what I've heard.

Anybody got a Sony and/or can enlighten me on what I need to pay attention to, etc.? I am horrible with computers, must admit. Thinking about just walking into Best Buy and getting this exact model. Never done it before though (my first one was bought to me by my ex-boyfriend, and I was never interested in details.) Any info (what to get additionally, any discounts, things to pay attention to, etc.) is really appreciated.

Thanks in advance.
