Typical book is less than 1MB; loads in a fraction of a second at USB 2.0 speeds. Maybe a second if you've got USB 1.1. Really not worth optimizing.

Type C USB would be nice. On the other hand, I don't have any type C USB connectors / sockets in my possession yet.

I'd really like a wireless recharging standard. Just toss your devices onto a surface and they charge overnight, it doesn't need to be fast.

Qi is that standard. Built in to lots of Androids now.

Only real issue with it is slow rate of charging. Not a problem for overnight recharges - but my phone still discharges when I'm using GPS + Bluetooth in my car's Qi holder.

> Qi is that standard

Unless you're at Starbucks, who have deployed Powermat/PMA. Even though Qi has vastly more support from phones and chargers (Toyota is even putting Qi in some cars), there's probably many more people who have actually used Powermat, just because of SBUX.

Sadly it's probably going away as newer nexuses don't have it.

Ebook files are generally not very large - my entire extensive collection takes up less size than one 30 minute h264 television show.

It's probably good enough

I'm sure micro usb is the required standard in Europe for mobile devices

It's still voluntary, though the manufacturers are pressured to accept it; but you can comply with it by having an adapter cable, like Apple does. Chinese companies are already selling them for <$2 a pop.
