Same here. It's barebones, but it's also cheap and plentiful on the used market, has enough functionality to be useful without being overwhelming, and fits easily in a backpack. Did some noodling around with it connected to my iPhone on a plane recently, no drivers needed if you get that Lighting-to-USB adapter, phone powered it fine, and I was able to drive Korg Gadget and make some shitty techno.
