The Performance is great. Not perfect for gaming but otherwise great. Battery life was much shorter than I expected.
ISSUES
There were initially many issues at start, such as the issue where the SP4 doesnt turn on. These issues however were finally resolved by a recent software/windows update. There is still 2 major issues affecting the surface pro 4 which prevents me giving it a 5 star. The battery life is poor; getting an average 4hrs, occasionally higher or lower. If youre someone who wants to take it a day out without a charger, I would not recommend this. The second major issue isnt entirely microsofts fault. The DPI(Dots per inch) is too high. In some ways, this is a good thing; clearer screen, better quality.
However, many applications(listing some but not limited to: autocad, photoshop, etc) do not support such high DPI. This results in either the text in the application to be too small(VERY SMALL), sometimes being unreadable, and sometimes even blurring out; ruining the quality. This issue however is not Microsofts fault but mainly the publisher of the Application. Unless these 2 issues are fixed, I wont give this a 5 star.
Who would I recommend this product to? Anyone who wants a nice tablet/laptop, doesnt need to worry about the money(premium price tag) and has a powerpoint to recharge this often. There are many other laptops with similar specs for a cheaper price if you think the price tag is too high.
