Wow at the sp4 hate. Live mine. Blazing fast, super convenient and low profile.
It isn't very hard to see why some people might hate it, if you are using it as laptop or as a tablet there are straight up better options.
Where the SP gains is in being versatile and allowing you to use both in the same package, but as a single thing it isn't great, I mean typing on the surface pro without the keyboard is straight up garbage, just a terrible experience even when you compare it to writing on something with a much smaller form factor like a smartphone, the tablet mode isn't always detected, the start menu in tablet mode is also pretty trashy, when you just want a laptop the IOs on it are pretty bad and who wants to go around with dongles, especially when the form factor is one of the SP main advantages.
Doesn't help that microsoft isn't particularly great at supporting their products, I mean even recently they released an update that was disabling facial recognition on windows, and it took them several days to fix it, when they could have just easily launched an emergency patch rolling back the drivers.
Now don't take this the wrong way, I absolutely love my SP4, it is a very good bit of hardware, but that is because one day I might be at home doing some electrical modifications and need something small that I can put in a shelf somewhere so I can watch some netflix, the other I might be out in the middle of nowhere and need to run some windows only software, or I might be needing to take some notes on some database design and it is more practical to take a screenshot and draw on it, than to print it out and write on the paper.
It is very versatile and well put together, but it is also a whole lot crappier than a tablet and a laptop when it comes time to use it, while being expensive enough that you can buy both.
Also it really cannot be overstated how much people tend to use shit wrongly, the amount of people I know that use laptops as desktops, when laptops are absolutely atrocious desktops is sheer insanity.
