[ubuntu] Ubuntu or Windows? So confused.

view story

http://ubuntuforums.org – Hi! I have just bought a Toshiba Satellite P850. Before that I used my mother's in law laptop (since I didn't have any at the time) and installed Wubi on original Vista (I hate Vista, fyi). Since then, I love Ubuntu!! Now that I've got my own laptop, that came with Win7 Home Premium installed, I am so confused to choose between Ubuntu or Win7. The reason being is that I am worried that Ubuntu won't be able to utilize the maximum ability of my laptop, like the dual graphics, the card reader (that I'm still unable to make it work btw), etc. Can anyone please advise me on what to do?
