Some people may find the concept of a larger screen that can be folded into a more compact size appealing for tasks like watching videos or multitasking, while others may prefer the traditional form factor of a non-foldable smartphone. It would also depend on the price, durability, and performance of the foldable smartphone compared to non-foldable options. **

Overall, I find the foldable bathtub to be a practical and versatile option for those looking for a compact and easy-to-use bathing solution. **
