Hi! I'm looking to buy a surface but I don't know which one to choose.. the hard drive is not important... and those one are the same price sp3 i5 8gb vs sp4 i5 4gb I'm not doing any photoshop or thing like that.. I don't think I will play game on it.. (I have an xbox one for that!! ) It mainly for taking note at school and working.. I already buy a docking station to have 2 screen.. Maybe I will sell my desktop computer to keep only one computer (the surface) What do you think? Sp4 with 4gb is enough? I plan to keep the surface a couple of years.. Thank you!
