    Dell Inspiron 7791 2 in 1 complete Review:
    If you are in the video game design field and looking for a laptop that will allow you to run your creative software at the same time as you are running your game-building software, this laptop will not meet your needs. If you are looking for a laptop that you can do 3D designing on this laptop will not support it. The video card will not allow you to be able to really build and see your graphics the way you will want to see them. If you are looking to only work in 2D and lower quality graphics then this laptop works great. But if you are looking for a laptop that won’t cost an arm and a leg and still be a beast in those quality design programs I would NOT recommend this laptop. The active pens do not work on it at all. In photoshop you can not use the touchscreen to draw or paint or anything other than zoom and move the focus of the screen, the only way to bypass this problem is to download a workaround app, and even then it is super buggy and sometimes doesn’t work. I got this laptop as a gift and the sale’s person said it was top of the line and all that jazz and claimed that dell stated that it was a designer’s dream, and active pen ready and great in 2D and 3D. But the laptop has done nothing but give me issues from day one.
