Just over a year ago, I purchased a refurbished Lenovo Thinkpad X230 off eBay. I've been using it everyday as a daily driver. It has its pros and cons which I'll go through, but so far, it has been the best laptop I have owned.
Here are the specs.
I have since upgraded it to 16GB DDR3 RAM and the other modification I have made is flashed the BIOS with Skulls. I wrote up an article on the Ministry of Nodes website for more detail on this modification and installing QubesOS. In the end, I opted out of running QubesOS - it was just too much for my needs and only had 8GB of RAM at the time.
In terms of operating system, I landed on Pop!_OS. It has the "it just works" factor to it. It runs incredibly well for all my needs.
In terms of pros, this has been the cheapest laptop I have ever bought. I'm expecting this laptop to last for a long time. Thinkpad's have a reputation of being built to last. So far, it's lived up to that, keeping in mind it's a refurbished computer. I like the screen size. Upgrades can be made with minimal fuss. Battery life is good for when I'm on the go as well. For all of my browsing and bitcoin needs, this laptop has been excellent.
In terms of cons, there's a few. My biggest gripe is the trackpad. It's just completely rubbish, but I am comparing it against a Macbook Pro. It has an old school VGA port, no HDMI port. The webcam isn't great either. The laptop itself is quite bulky and thick.
I would like get a new laptop at some stage, but a couple things hold me back.
Some features I'd like in my next laptop would be a better trackpad, slimmer design, higher screen resolution and USB-C charging.
But for now, I will continue to use this one.
