It depends what you want to use it for. It doesn't have GPS, or a camera, or NFC, so you won't be using it to navigate, take photos, or pay for things. You also aren't going to have much fun using it to make phone calls, and it won't run Android apps - at least not without a serious investment of effort. It also runs warm, and can only sustain 8 hours or so of screen-on time.

That said - yes. Folded, it's almost exactly the same size as my Unihertz Titan smartphone. Open, it is an extremely capable machine for googling things, buying tickets to events, checking train times, chatting on WhatsApp, watching YouTube, and wasting time on Reddit.
