I'm just sending this from my own Yoga Tab 13 2021. Actually paid 565 EUR for the 256GB version. Quite happy with it. I gifted my dad a Yoga Tab 8 many many years ago and he was enjoying it for the longest time, I kinda got impressed by it myself and bought the Yoga Tab 3 Pro 10.1" with the projector. That was a lovely little thing, but after using that one for the longest time, it was starting to show its age.
Not actually too long ago then I went with the Yoga Smart Tab 10.1". Sad not having the projector, but it was a welcome improvement overall. The audio was phenomenal and it was an awesome companion. My moans with that one though is that the kickstand was no longer freely adjustable, it had fixed positions for example. Also, the screen is a little too small for what I also was using it for: as an ereader for my Readly magazines.
This 13" sure takes things to the next level. I enjoy taking it with me when I'm away from home for a short while and don't feel like bringing my laptop (I'm using it with the BT Universal Microsoft Modern Design Keyboard and Mouse). The sound is good, however, weirdly enough I feel like the sound out of the Yoga Smart Tab 10 is slightly better.
Definitely wouldn't have paid full price for it. And I still think I've overpaid with 565 EUR. But there's nothing really quite like a Yoga Tab with super versatile kickstand (super underrated!) and JBL speakers (great immersion). Would be kinda cool though if they could bring back the projector function in a next one!
