A laptop is a compromise, only buy one if you need a laptop, otherwise use a desktop.
How much are you going to spend?
On a warm day, I take my laptop out to my picnic table on the deck (hint: on a bright sunny day, use an empty cardboard box turned on its side to reduce sun glare.
A 15-inch screen is perfect for a laptop.
“A laptop is a compromise...”
BS...I retired desktops years ago and do everything with laptops. There is no reason for a desktop if you are not a supercilious gamer, or think your desktop is gonna be a server (which it won’t be).
And there are times when any of us ‘need’ a laptop. I need one when I want to go to another part of the house and use it. I need one when I travel.
And btw, there is no excuse for ‘loosing all my data’...it is called backup! Backup can easily be done to an external hard drive...they are not expensive. Backup can also be done via ‘cloud’ and this is available various ways...Norton, a very good security system, has it available.
