For example RT
Surface are dreadful tablets.
Rather no. Not at all RT. Surface RT is a complete junk and also out of date. What do you want to do with Surface RT if you can only use tile apps from the Windows Store and not normal programs (like Firefox, VLC, etc…)?
So if you already have a powerful laptop, then Surface Pro makes less sense, unless you want to have not just one but also two Windows laptops.
The Surface RT was much more horrific
As so often, it depends on what you want to do with it and whether it fits into your financial framework…
I have a laptop with a lot of power… In addition, a Surface Book and for a year now the Surface Go2 … I use the little Go almost every evening on the couch, sometimes in the garden or on the go. Both my book and the other laptop are definitely too heavy and unwieldy for on the go…
However - I would definitely not buy an RT today (we have one) … That is 9 years old… And you can't install "normal" programs because the RT is a closed system…
