let me preface this by saying, my husband and i do not have cable. the $8 we spend each month (currently on netflix) is pretty much what our budget will allow as far as television goes. we don't watch very much (a few evening shows), and the few we do watch we tend to go to the gym to watch while we do our cardio.
that being said, i'm trying to decide if we should keep netflix or drop it for hulu plus. they are about the same price and both can be streamed thru the wii. we've had netflix for several months, and i love it (for the most part - except when they drop a series that i'm half way through). they do not offer current seasons of shows though. but they do have documentaries (which my husband and i are nerdy enough to enjoy on a regular basis) and zero ads. hulu plus claims "minimal ads" but also episodes of shows we watch up to the latest episode aired.
we will probably start the week long free trial of hulu plus so we have it through his spring break week (coming up in a few weeks) when we have more time to hang on the couch.
er... yeah, basically all of that was a long winded way of saying which do you prefer, and why? :P
