It's possible that you haven't actually seen a real hologram. It's quite impressive. The ones I have seen are 3-dimensional objects in the air in front of you, and you can walk around it, typically not the full 360 degrees, but it's just.. there. It's nothing at all like what we normally call a "display".
But not sight-read when playing an actual instrument.
Anyway, that problem is long gone.
It's also useful in that you can pre-order a Shinkansen ticket, for example, and link that purchase to your Suica card, which you then use for the Shinkansen gate. If there are other fees (which there may be) they're just deducted from the money the card holds, as usual. Makes everything very simple.
For me a physical card is easier than using a phone. A phone is so much larger so I would need to get it from a pocket somewhere, while the Suica card I can keep in my jeans pocket or some other easy place.
Zigbee is basically the same everywhere, however the 2.4GHz band is of course somewhat congested.
And when I've tried navigating in large cities (Tokyo included) and found that my stupid tablet's GPS relied on getting the ephemeris data from the internet, and never through the GPS itself, I couldn't start navigating until I connected to something.. and I spent hours trying to find an open network, unsuccessfully. Happened twice, the second time in Nagoya. No open networks. Well, Starbucks have that, but then you need to find one.
