I'll take the Yoga Book 9i instead. Just like dual display on smartphones, you can easily use any two apps simultaneously without having to worry about split screen incompatibility. It's the same reason I sold my Samsung Galaxy Fold and bought an LG V50 with its detachable Dual Screen case. Suffice to say, it's one of the best decision I've ever made.
I'm glad they finally released the device, but I don't see an option on their website to upgrade the battery. That is a shame as the reviews showcasing the initial design in 2022 included that as an option :(
Lenovo's second-generation ThinkPad X1 Fold is now available to purchase, a year after its initial showcase. In the intervening period, Lenovo has made various changes to the device, which still carries a US$2,499 starting price.
