I own a Traveler and L-O-V-E it. I’ve wanted to get a Smart Typewriter for awhile for home use, where I often write in low light levels. Or sometimes even in the dark. I didn’t think I could like a keyboard more than I do the Traveler, but I stand corrected — the Smart Typewriter keyboard is even better. The few shortfalls I found with the Traveler are almost non-existent with the ST. The light is a perfect level for use anytime — bright, dark, and everything in between. And for me, this is the biggest complaint about the Traveler — I can’t use it in low light or dark (Though if a light was added to the Traveler, I would prefer an on/off switch instead of always on, like the ST). The lag between keyboard and screen that the Traveler has is almost gone with the ST. I notice it a little bit at times, but for the most part it’s not there. And since the WIFI can just be left on all the time, I find the syncing to be much more reliable. The only thing I’ve found so far with the ST is more of a user muscle-memory type thing: the space bar is very pronounced, and if I hold my hand like I normally do on all of my other keyboards, my thumb rides the space bar (I don’t notice it, it barely touches it), and so I get random spaces throughout my draft. A lot of them. But this isn’t something that’s the ST’s fault, it’s just something I have to be aware of.
