I'm an absolute noob, but I would have a new notebook / laptop (not even the difference I know.) Grow. The following is what I do with it in the first place:
stream (music, movies, etc) this should run smoothly
Write Applications
That was it by and large eig., Otherwise it should have the following characteristics:
not too big, handy, thin
HDMI connection
relatively much memory for pictures
There are actually only very amateur data on my part, but you vllt have great suggestions for me, which are not too expensive. (up to € 400,00 but of course also happy)
To judge if he suits you, you have to specify size, weight and age.
ask aunt google, if there's a contact exchange for laptops.
If you do not necessarily need windows you can search for Crome-books.
Weight does not matter to me, I'm very tolerant. Age too, should not be too worn. Loyalty is also very important to me and humor.
Laptops have monitors that are at least 18 "diagonal, so they're pretty rare.
Laymen should definitely go to a shop and get advice there and logically buy there as well.
