My personal thoughts are that for indie developers, we provide a totally free way to watch *every* session online in < 24 hours. That's unheard of in our industry. The total cost is $0.
If you are an indie developer, then I totally understand the importance of reducing costs. Traveling and airfare to an event can even cost as much as a pass to a conference like Build ($250/night for hotel, $400-1,200 on airfare depending on domestic vs international, food, etc).
If I was an indie developer, I would:
Watch the live streams and ask questions during live Q&A
Watch all the sessions that are relevant to me
Attend FREE Microsoft training like our 1-2 day dev camps on Windows, Phone, Azure, Web - http://www.devcamps.ms/. The best thing about these camps is that they are so many that you may not have to incur any travel costs to attend.
