They didn't stress the SP4 enough, during their quality control, I guess and it sucks. There shouldn't be a i7 version then and they certainly shouldn't be advertising it as an AutoCAD and Photoshop machine. A medium sized 3D model in AutoCAD makes the PC
run hot. I use Bitwig Studio because I love music and using it with about 15 tracks with some plugins stresses the SP4 a lot. That's why I bought a 8GB RAM, 256 GB SD, Core i7. 1600$ wasted in a 1.5years.
Now I can't push the SP the way I need because it flicks even with the seconds in the clock running. If I turn off the taskbar the shaking starts automatically after seconds of not doing anything with the SP cool as ice. In the end, it's getting worse and
without an answer, I feel cheated.
I'm Bolivian citizen, 30 years old, civil engineer and I've been using windows since 95. I bought the SP4 because I believed that this tablet could replace my laptop and It did while it was working but now I can't push it and I'm stuck with a 1600 $ Facebook
machine. I used my hard earned money and this is my only device. Microsoft should be ashamed! They must give us a definitive answer, I'll help them, they can say something like this. "The SP4 has hardware issues and If your warranty is expired, you should
be looking to buy another PC" That's it!, then I can start saving again to buy something else and stop suggesting this product to people I love.
I tried to spread this issue in mspoweruser and windowscentral because some people are looking to buy second hand SP4s because of the new SP, but no one seemed to care and I even got downvoted a lot in WC. Guess they will have to experience this issue themselves.
I'm praying for Revit and at least one good structural analysis software to be available on mac and I'll be all in on a MacBook Pro.
I'll be silently reading this forum but my hopes are gone.
Good Luck to everyone!
