I haven’t used other handhelds, but what you say is what I’ve seen from other discussions and reviews. Yes, there are more powerful systems with better screens, but the SD’s OS is miles ahead (but not without a lot of quirks as well). The touchpads are incredible - I couldn’t imagine trying to use a handheld PC without those touchpads. Also, the custom control configuration abilities built in to steam OS are incredibly versatile and detailed.
