I gave it a shot the other day then locked it away in my room again. It's just a bit too small for my giant hands. D-pad heavy games hurt my left thumb.
What, it doesn't even have rumble? What was the point of removing that... The haptic motors used in the JoyCons may be a bit bulky, but there are much smaller ones used in smartphones. Weaker rumble is better than no rumble at all.Switch Lite lacks a couple of things - rumble, HDMI output, IR port. Obviously, "joy-cons" cannot be removed and face buttons feel a bit spongy until you get used to them. Just like any Switch other than unpatched Erista models, in order to have access to CFW modchip needs to be installed previously.
It still has Amiibo support and the form factor is much better, suitable for a portable handheld. It has a D-pad instead of buttons which is a bit better, but it still feels a bit spongy. I do like the feel of the L2 and R3 triggers, though. It also supports USB controller, however useful that may be.
Overall, it's a decent handheld and I love it for what it is. I love playing Animal Crossing on it and official NSO emulators on it.
Recently an OLED kit was released for it which additionally allows you to install an HDMI output mod as well, depending on if you go for the biggest kit.
