I agree guys, things need to improve on the G2 to make the G2 Solo more compelling for the masses, but I am hopeful. Heck, I may be compelled to even buy the G2 Solo today if it's available, even with the current state of SVoice, but with a better battery life since I average about 50 calls/day and would like to check/reply on many emails. As for its small screen size, I used to do think composing email, visiting Ebay, Amazon, etc were not practical on my old Note2 compared to my desktop or tablet, but I have learned to adapt, and now I do everything on my have GS5, minus word processing and heavy web browsing.
As for any wrist-phones, they are a great idea, but I believe many do not have voice recognition like SVoice or Google Voice. Another one I have researched is Burg, but they are ugly looking, you can insert your sim card on their unlocked devices, but biggest turn off for me is their 3G limitation.
