Which MacBook Pro should I get?

I have a Lenovo Flex 2 right now and it's the worst laptop I've ever owned. It's nothing but problems so I decided that I wanted to transition over to Apple because I just really like their products more. I want to get the MacBook Pro 13 with retina display and 8gb of Ram but I'm stuck on the storage. Should I get 128gb or 256gb? I'm going to down load Microsoft office for Mac on the computer for school. I also have a lot of music and photos that would go on this computer. The 256gb is three hundred dollars more so I need to know is it worth it or should I go with the 128gb and just buy an external hard drive?

Can I return my laptop to BestBuy?

Can I return my laptop to BestBuy? - 1

Added (1). I've had this laptop for about 3 months. I've hardly used it, there's not a scratch on it. After a month of not being on it, i go on it and noticed my battery was fully charged. I unplugged the charger and the laptop completely shuts off. As I turn it back on, the desktop says that my battery is damaged and i need to replace it. I have no clue how this happened, I have never spilt a drink by it, and i'm hardly on it. Does BestBuy come with a 1yr warranty when buying a Lenovo Yoga Pro 2 laptop?

Lenovo laptop charger not working? Fixes?

My lenovo laptop charger isn't working. I've unplugged it and plugged it back it, upside down and all that junk. The only way it works is if the laptop is closed and leaning against a wall so that the charging area is on the ground, if that makes sense.

is there any way I can fix this?

My laptop won't boot up properly?

I turn it on, and it goes to a blue screen with a big. Face and says it has failed to start up properly and needs to repair. It then restarts and says it's preparing automatic repair. Then it says it's diagnosing. Then it ogre to another blue screen 'PC did not restart correctly, restart or press advanced options'. I have restarted it many times, is there a way to fix this without a separate disk or anything, maybe by using command prompts? Thanks
It's a lenovo laptop Y50-70 with windows 8.

Computer Science student looking for a new laptop: Lenovo VS ASUS?

I will be heading off to college in a month and am in need of a new laptop. I'm going to be studying Computer Science, so I will mostly be using this for programming.

After researching online, I'm looking between Lenovo & ASUS. They both seem like the best choices, but I'm still stuck. What are the pros & cons of getting one over the other?

(Side Question: Would the Surface Pro 4 be any better than these two for a Computer Science major?)
