I seriously considered buying one of these six months ago, but the lack of Wi-Fi ended up being a deal-breaker for me, unfortunately. It is possible to add Wi-Fi using a microSD chip, but then I wouldn't be able to expand beyond the 2GB of on board storage.
It still looks like a fantastic product though. I'm really looking forward to seeing a future Nanonote with Wi-Fi built-in.
From what I heard the v2 (which would be called Ya NanoNote) lacks funding and is far into the future. Most efforts currently seem to be concentrated on the M1
