I quite like the design, but then again I did have one of those music centres and I loved it.
Not sure how the battery manager reducing capacity to 80% helps? Is it just a case that, as a battery loses about 20% a year anyway, the first years loss won't be noticed because it always ran at 80% capacity? e.g. "I bought my laptop a year ago, it had 2.5 hour battery life then and it still does today!"
Sounds like smoke and mirrors to me.
