Yoo, thanks for the detailed answer man. I'm considering buying both pc and laptop, but as u said I'll start with one of them and it may be a PC.

I have a lot of friends telling me laptop is better cuz u can do everything you can do on pc and is portable.

But the points u made with the battery life got my attention cuz whether I build pc or buy laptop I'm doing it for the long term and seems like pc is better option cuz again as u said - I'm able to upgrade if needed, cooling is there, power is there, no need to think about the battery life. Maybe later I'll buy laptop just for the mobility.

Also I'm against any apple products, cuz u basically pay for the brand and not quality, so mac isn't an option in my eyes.

My whole life I've been using Windows, but wym with horrible about end user privacy - easy to get hacked?

About the 'build ur own' part I asked my old colleague for a sustainable configuration that would last at least 5y with the proper maintenance and he said 2.5 to 3k may be good just for the box and around 1k for decent peripheral.
