Plenty!  The major drawback is the short Main Sequence Lifetime (when 
it is stable, burning hydrogen into helium).  For the sun, the MS life
is estimated to be 10 billion years.  For blue-white (very hot) stars
like Sirius, the lifetime is closer to Millions of years, hardly
enough time to get any serious evolution started.

Also due to the higher temperature, the star would be producing more 
light in all wavelengths, but most of it would be in the Ultra-Violet,
not good for life as we know it, but who can tell what little bug-eyed
monsters might enjoy?
