For all my outdoor activities, in the backyard, the garage, the front yard, I listen to boomboxes exclusively. When inside the house I use a boombox 70% of the time. The other 30% is my audiophile home system, usually wearing headphones (Sennheiser HD800) because it is way too loud to listen to the way I like it...

. When I am at the basketball court I use my M70 or M90 only, because they are my best outdoor boxes. Those 2 have the best mix of quality sound and volume.
With the addition of the Sony FH-207 I am using my home system less and less. The only time my home system gets used now is when the family is in the Theater Room watching a movie. My Theater is equipped with an Onkyo 7.1 surround receiver, Bowers & Wilkens mids and tweets, and Velodyne subs in every corner...even with this insane system I prefer boomboxes. All six bedrooms in my house have a boombox, I have thrown away all the eggs that used to occupy the rooms. So basically everyone in my family uses a boombox as their main choice for listening.
My daughters box of choice is her custom Blockbuster, my son prefers his Panny CS 780, my wife the JVC PC-V2J, and I prefer everything else!!
Lately the best part about having boomboxes is all my friends and my wifes friends always call me when they are having a bbq or outdoor party and ask if I can bring over a couple boomboxes to provide the music! So I love the fact that my boomers get lots of play. There are no shelf queens allowed in my house!!
