Yep. There's also external battery packs, which probably not a problem for some jobs.
However, there were some other issues I encountered in previous (early) Google Glass development that I wonder if they have been resolved:
- Google Glass devices were prone to overheating to the point of shutting down, so it was not possible to do anything terribly computationally intensive.
- Support for more corporate oriented wifi protocols (eg LEAP) was marginal; the Glass even had trouble making an initial connection to a hidden SSIDs on a standard WPA2 network.
- Barcode scanner support is based on camera image capture; unfortunately small barcodes were difficult to impossible to scan with the Glass as a result (both due to the need to position the code close to the camera, and the nature of the camera that made closeups of small barcodes very blurry).
