Never say never... I got the first generation iPad, and was happy that I did. But then, it was not that expensive. But yes, especially with such a new product category, you really want to wait a few generations, if you want to get the best product for your money. Just look how quickly iPhones evolved and this Vision Pro is even more groundbreaking.
As I said, I was happy. In the end it is always the relation on how you balance quickly vs. spending money on a first-gen product. But yes, most iPad customers probably were happier with the 2nd gen.
