In the V2 box you get a mono headphone, and the Glass itself as well as a very large not so handy bag, along with the usual charger and stuff.
With this order I got the additional headphone backings which have all sorts of lovely colours.Set up is really easy, after charging Glass (I'm assuming they all come with sod all power inside) its a matter of establishing a connection to the WiFi - done with some setup on the web and then pointing the Glass to read the resulting QR code.
I cant really comment on the XE12 or XE11 code for some reason this unit is stuck on XE10, something Google were not able to fix just yet. So please keep that in mind until I can get that resolved, this is strictly a cover of the older firmware :( boo.
For now the Google Explorer Edition requires you to have some working knowledge of Androids deeper workings, so if you want to install sideloaded apks from the community - you will need the Android SDK and turn off a few Windows features. You can follow the You Tube video here http://www.youtube.com/watch?v=rfpKyj7fJCM or watch at the end of the blog post for more information. Also a handy resource is Applied Glass, a good few guides to be had with installing USB drivers for Glass. I doubt very much the final retail version will be this so involved though.
Before I can get into allot of detail (at a later date) I will leave you with a few comments about Glass itself. I really like it, it does have some fantastic programs being developed for it, its pretty light and you can easily forget you are wearing it. The basic features of calling, navigation, taking a picture / video are all there, texting and making a call too. You can speak out replies to G+, Texts etc, there is also a Whatsapp relay service called WhatsGlass which works well. You can have news stories pumped to your eyeballs but one item I do like is the ability to translate language using Word Lens - shame it doesn't work when driving but hopefully that will come, maybe it doesn't have time to read signs.
One gripe I have so far is Glass doesn't like my London accent very much so I have to do the reverse of Dick Van Dyke and do my best Texan accent, with mixed results. Navigation is very good and Telephone calls are clear although the speaker behind your are tickles / annoys sometimes, once its turned down below 100% or the ear bud is plugged in the problem goes away.
I couldn't help but troll the local Apple Store, something the child in me couldn't resist. It did give me a chance to test out the camera which is surprisingly good.
Anyway I will update further as the days / weeks / months come along and pass by. If you have any questions then feel free to ask me, Ill do my best to answer them in the chat box below.
The promised video is below for the install of Google Glass USB Drivers on Windows 8 (which I may add, is shit, Windows 8 that is)
