i am using Dell Laptop and Apple i phone am using... According to my opinion these are the best company for mobile and laptop, and their performance is also excellent.
Sorry but Dell Brand laptop?yeah it is your Opinion or maybe that is the first laptop that you use so there is no comparison because if does for sure you may choose other brand like Apple Mac and or even Lenovo but not dell.
Anyway sometimes it is depend on our usage and budget.
I use Toshiba Laptop long ago, and Infinix for smartphone
Infinix Note's are cool have seen that in one of my office mate.
