So I'm an undergrad and im gonna need something new and STRONG (no viruses and screens sensitive to breaking) to last through the rest of my time in school. Both my laptop and netbook ruined the same day, both Toshiba, so now i just want whats best quality

So, I need opinions on what is better for university students, I dont want to regret my decisions. I want a MB Air but its a bit pricey, but I feel like i can do less with an iPad than with a laptop. If i get an iPad, then I can get a Bluetooth keyboard
I DONT EVER WANT TO BU ANOTHER PC EVER IN MY LIFE -___-

but between these, i dont want a mac book pro. im gonna be carrying it everyday, so these 2 are light weight
