Welcome to ECF and the world of vaping! I think you will get a great start with the Blu thanks to all the tips and tricks you have been supplied with here. My first vape was back on March 17th. I personally started with an e-pipe since I was a pipe smoker. I then moved to mods, passthroughs and the eGo. Tonight I am having my first experience with 5v on a passthrough that I just built out of an old usb cable and a dead eGo battery. Hardly anyone stays with just the first pv that they started with. Most wind up with several different types and styles in their collection. I still use all of the types that I just mentioned (except the pipe which died after 6 months, but it will be replaced when my money supply can handle it) as well as the occasional regular 510 ecig. The variety seems almost limitless. I am sure you will enjoy your blu as well as the eGo when the time comes and any other pv's that you end up with as time goes by.
Have fun and remember, mailman stalking is a normal part of the vaping experience!
