Not quite, and for various reasons. What would you want by way of input on such a device? I've been working on something like this based on TI OMAP CPUs, and the hardest thing (after a decent semi-open SoC) is getting a decent keyboard. I think the N800 was probably the pinnacle of handheld Linux devices (or the Psion 5 series if you step outside of Linux). You could look at the Raspberry Pi handheld game console options out there, but ultimately there's little that can compete with a Pi Zero, battery pack and ILI9341 screen on price.
