Are you saying that Surface Pro 4 is not a premium product ?
I never said that, so I do not know where you got that from. I said SURFACE DEVICES, which is plural so I really really can't see where did you get that from. Not everyone is responding to your comments only
Tell me what Surface Laptop does that Surface Pro 4 cannot do ?
It's not about can't or cannot, but
how well. Surface Laptop has newer generation processors which include newer generation integrated graphics. It has different speaker system and it's lighter. You don't need to purchase a type cover separately and here I'd like to point out that in Europe Surface Pro 4 is more expensive than in the US and Canada. Some people don't need the Pro version of the system, because with the office available through the Store they can get a lot of applications.
This is not a gaming machine and not intended to be used with pen (it can be used with pen, but it's not included like with the Surface Pro 4), so any apps for artists like Adobe Illustrator or Corel Draw are not intended to be used on this - MS made Surface Book and Studio specifically for people who need more power for their work, especially with pen.
What I wanted to say is that MS was targeting different groups of people with their products. Yes, Surface Pro 4 is used by students too, but I guess some don't need any apps outside the Windows Store, mainly do just browsing and use Office, don't want to use type cover or don't need a pen, even if I almost can't imagine not using a pen if it's available for notes.
It's simple - want a traditional laptop and don't need any apps outside Windows Store (but can upgrade to pro anyway) with latest generation of Intel processor that is also good looking and you have money?
Go buy Surface Laptop. Do you want a device with 2 year old processor that is mainly meant to be used as tablet but can also function as a laptop with the type cover and you are a big pen user & also need apps outside Windows Store and is also good looking? Go buy Surface Pro 4.
