Hi guys, I am photographer and sometimes I do video editing on high end softwares like adobe and final cut, I have the 5K IMAC as my main computer which i do all of my work on but unfortunately i travel a lot (pilot) and most of the time i do my photography out of the country, I had a Macbook pro but I though of how heavy it is so I sold it. Now I am long time apple consumer more than 10 years and I was hopping that iPad pro will be any way pro but end of the day its just an iPad with a bigger screen which i can not run any of my photography software on like Lightroom and photoshop and not to mention the ability to transfer my photos from different kind of memory cards on the go..... I made a long search on the new surface pro 4 as its attract me from every angle and not to mention its has the full OS system that i need for my usage, but there certain things i couldn't find an answer for and i was hopping someone with past experience with MAC can answer these question for me: 1- is the Microsoft system as responsive as apple from trackpad input and scrolling through browser and zooming in and out without a lag coz MAC handle that in a good way ? 2- I heard a lot of bugs are they fixed coz i don't want to work on my project for hours than has to restart my device because of bug? 3- how responsive is the pen in photography usage for correcting highlight and shadow and major exposure change in photoshop and light room if any photographer can help? finally if I am buying the device do i need a screen protector as i will be heavy user with pen so any scratch is expected from the pen needle? I thank you again guy and really appreciate your help here and specially photographers if any i would love to hear your thoughts as I am less than 2 days to pull the trigger on the device.
