Hello there, First of all, an apology for what will probably feel as a 'here we go again'.. I am a simple teacher and student. I would use my mb for tasks as: - PPT/Prezi multiple instances - Word multiple instances - PDF multiple instances - 20 or so tabs in Safari - All of the above at once - Worth mentioning I have a 1TB online storage with STACK Would a base mb last me for ~4/5 years with my usage. (Ofcourse newer things will come out doing it faster, but that is not my concern as long as my mb is up to the task) Would you advice going for an i5? Would you advice going m3 with 16gb? Basically, what would you advice me? Thanks in advance for your time and patience.
