Re: Cheaper alternative Thinkpad
Except, as you say it's over 17% heavier and takes up less space.
My main PC at home is a self built desktop PC with a Ryzen CPU and 32 GB of RAM. I use my laptop for web browsing, writing docs etc and occasionally building a bit of code.
If I needed to give the CPU and RAM a regular workout I'd probably have to get something different but the X1 is easily powerful enough for my needs. It's also very small and light, which is a big deal if you travel with work as I do. If I'm flying somewhere for a meeting and only need to stay for a night or two my spare clothes go into my laptop bag. Every cubic centimetre and every gram counts.
People have different needs which is why different options exist. Most of my colleagues use Macs which cost twice as much, because for some reason they feel they need one.
