hey akul, id say portability for me. my current laptop has 2 usb-a ports, an sd card reader, ethernet port, mini display, audio jack, and firewire port. how many do i use? 1 usb-a port and the audio jack. i thought having the ports would be great which is one reason why i got my laptop, but after a few years of using this laptop i dont even touch most of them. however, the reason why i use my laptop as a desktop is because of its weight and thickness. i want to take my laptop to work but dont want to carry that heavy computer, but a slim laptop like the surface laptop is almost half the weight of my current laptop which makes for transporting it much easier.
