I've played both of those at music stores because they looked interesting.

They're great if you're always playing amplified and you prefer that sort of processed, quack-like sound that transducer pickups provide. Some people actually like that sound. But if you want something that sounds like an actual guitar (resonating wood), look at actual guitars.

If you're looking for something small that travels well, sure, those things are great, but remember that you also must bring amplification, thus increasing the travel complexity by that amount.

Another travel guitar option is a Baby Taylor or a Baby Martin. They don't sound like their full-size counterparts, but they do sound good, and they're really cute and feel great.
