Apple to pointlessly reinvent computer (6)
I believe the answer is:
laptop
'computer' is the definition.
(laptop is a part of computer)
'apple to pointlessly reinvent' is the wordplay.
I cannot really see how this works, but
'to' is found in the answer.
The remaining letters 'lapp' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for laptop that I've seen before include "Kind of computer" , "Aid for businessman" , "Type of computer" , "device?" , "PC" .)
