Do you think 256 GB Flash Storage is enough? These 2 prices are affordable for me. I also have 1TB external hard drive storage. I will use the laptop mostly for school work, surfing internet, emails, watching movies and listening musics. I am also concerned about rmbp doesn't have a external internet port. It's really hard to decide because 1.I'm new to Mac product. 2. The prices are not quite different from each other. Thanks in advance.
