I have an Asus Zenbook Duo (2024) but I wouldn’t recommend it.
Coming from a Surface Laptop Go 2, and a Surface Pro 8 before that, the build quality on the Zenbook Duo feels worse. Even a Zenbook 14 OLED (2024) that I purchased around the same time seems like it has better quality at half the price.
The Bluetooth is finicky, it has no Miracast support, and the wireless keyboard battery seems to have degraded considerably in just a couple of months, to name a few issues.
There’s also questionable design choices, like not making the pop-out stand run edge-to-edge the way Surface does, and not including any way for the keyboard’s top portion to anchor itself when placed on the secondary screen, among others.
It’s like a beta product at a premium price, but the form factor is definitely what appealed to me. Sadly, there’s not many other choices in that area, except for the Yoga Book 9i and maybe a MacBook with an iPad anchored atop the screen.
I found them after Mint was discontinued and CreditKarma made it impossible for me to set up my account, while I looked into other options which have even been mentioned in this thread.
LunchMoney's multi-currency support and easy API (https://lunchmoney.dev/) were killer features for me, however, since they allowed me to develop a personal solution to also keep track of my non-USA accounts.
