My Current Thinkpad
In 2018 I reviewed a Thinkpad X1 Carbon Gen6 that was assigned to me for work [1].
In April last year I wrote about the failings of my Thinkpad Yoga Gen 3 and how I was going back to the Thinkpad X1 Carbon Gen5 [2]. The Gen5 in question has 8G of RAM and a 1920*1080 display compared to 16G and 2560*1440 for the Yoga but runs reliably on battery without crashing. The Yoga in question has been used by relatives who don’t need to do much when on battery and is currently being used by a relative who runs Windows so the occasional crash is something they are used to.
In mid last year I bought a Thinkpad X1 Carbon Gen6 for $350 which has 16G of RAM and a 2560*1440 display. The higher resolution display is a significant benefit and while 8G of RAM is still usable for medium to heavy Linux desktop use it does cause problems sometimes. The new laptop I now have is significantly better than the one I had for work in 2018!
I realised that my previous review of that laptop was incorrect in one aspect, there are two USB-C ports it’s just that one may be covered by a rubber stopper when you get it. When I received this one the Ethernet dongle port was covered by a rubber stopper and the seller was unaware of the possibility of using a dongle and didn’t have such a dongle. It’s not a big deal as I have a collection of USB Ethernet devices but would still be handy to have while not worth the $20 it costs to buy one (a 2.5Gbit USB Ethernet device cost me $16 two years ago).
Laptop Displays
Today I saw a Thinkpad X1 Carbon Gen9 with 3840*2400 display and 16G of RAM for $550 on Facebook marketplace, which is a very tempting deal. 3840*2400 is 2.5* as many pixels as 2560*1440 while 2560*1440 is only 77% more pixels than 1920*1080. So if my eyes were able to properly distinguish pixels that that high DPI then the benefits of getting the 3840*2400 laptop would be greater than going to what I currently have from FullHD. But as a 1440p display in a 14″ form factor is already past the stage where I can see individual pixels the benefits of 4K are more about making curves more rounded which improves readability and allows slightly smaller font sizes but doesn’t give anything like the benefits that going from a FullHD desktop monitor to a 4K desktop monitor.
Also I have different usage patterns for my laptop than for my desktop. I use my laptop for reading blog posts and ebooks for which even FullHD would be fine as the amount of text that can be usefully displayed on screen isn’t that great. I also use my laptop for emergency sysadmin work, ssh to a server to restart a daemon, run ping while changing network hardware, and other things where I don’t have a lot of text on screen.
I also use my laptop for light coding tasks while watching TV. It’s not possible to effectively do complex debugging tasks while watching TV or while using a small screen. But a very large portion of coding time is spent dealing with things like testing builds with different versions of libraries, applying patches to a new upstream release of software, fixing issues related to functions being renamed, testing to see if a new version has really fixed a bug it’s supposed to fix, and other things that don’t require a lot of skill.
I am not claiming that 4K displays aren’t great for laptops. Merely that at the current time it’s not worth $550 of my money.
Future Thinkpads
I like the Thinkpad X1 Carbon line and plan to continue buying them as they get cheap.
The Gen11 is the first one to have a minimum of 16G of RAM, the reason this is important to me is that the ones I buy aren’t the lowest model because I want more than the minimum display resolution. As people who get above the minimum spec in one area tend to get above the minimum in others that means that there will be plenty of Gen11s on the market with 32G of RAM when I’m ready to buy one of that era. Presumably by that time Linux software will have become more bloated and make me want more RAM. Yes soldered RAM has some downsides, but if you want an ultra-light laptop it’s a trade-off you need to deal with. One problem with the Gen11 is that the maximum display resolution is 2880*1800, it’s still a reasonable improvement over what I’ve currently got but not close to the 4K I desire.
The Gen12 has support for 8K display at 60Hz over Thunderbolt which is nice. By the time the Gen12 is in my price range it’s quite likely that I will have a monitor with higher than 5120*2160 resolution (the maximum video out resolution of Gen11 and previous models in the Thinkpad X1 Carbon range) on my desk.
The Gen13 still has 2880*1800 as the maximum resolution but has OLED as an option.
So it looks like a Gen9 or Gen10 may be ideal for me as they are the last ones in the Thinkpad X1 Carbon series to support 4K displays. Another option is the Thinkpad Yoga Gen8 which is of the same era as the Thinkpad X1 Carbon Gen11 but has a 3840*2400 OLED touch screen, I might be able to get one of those cheap with the touch screen damaged.
