There may any one help me with a laptop choice because am new to elemental os
There aren't many laptops that have any sort of official support for elementary OS.
There are brands of laptops that come with a Linux distribution pre-installed. Those likely also work fine with elementary OS. For example:
The majority of laptops that come with Windows preinstalled can run Linux distributions like elementary OS with little to no problems. Some may require additional fixes to get Wi-Fi and such working. Very new laptop models that come with cutting-edge hardware might not fully function on Linux (yet) or require you to install a newer Linux kernel.
To find information about the compatibility of a specific laptop model you'll have to do some research yourself, and/or ask the manufacturer.
elementary OS is based on Ubuntu, so if a laptop works well with Ubuntu, it likely works well with elementary OS as well.
https://puri.sm/ will prob work fine since it comes with PureOS pre-installed, which is also a fork of Ubuntu afaik.
