I personally like my macbook, she can get student discounts for it too.I've had it for about 3 years and I use it mainly for netflix and school work too and it has been very useful. I don't have any problems with viruses or lagging. I use it all night and it's really durable. I don't remember the last time I've shut down my mac as I always watch netflix before bed and it ends up playing throughout the night (oops), yet it hasn't affected the laptops performance it any way. Also, I like the designs of the macbook, unlike other laptops I don't think it ever looks 'old' and obsolete. They are also fairly compact and light, especially the macbook air and the smaller screens macs which is useful when travelling in uni.
