Input:
It works as described, package included 2 AA batteries, 1 set of earbud, SP90 and a piece of document. Most sub-100 MP3-CD players I've found at local BB and CC looks really cheap, this one does not. It also looks thinner. The rubber surface looks durable. The earbud could be better. One nice thing to find is that when playing MP3s, the CD spin a couple of seconds, feed the data to the buffer, and it stops spinning and play through the buffer. That way it saves both the batteries and the skipping.
Actually I think it looks better than its flashy bigger brother, the SP100, also thinner. I really liked the low-profile looking, though I will like to see more color options.
Lacking the rom-update-capability really does not bother me. Hey, it's not some M?cro?oft that needs repeated update for bug-fixes. Back-lit is not neccessary since most of the time the piece is sitting somewhere other than my hands, I can not see the LCD screen anyway. Case and LCD remote will be nice, but I won't say that plus the FM radio will justify the price difference between this one and SP250, but the 8Min buffer will be really really nice.
The only reason I did not rate it as 5 is I don't have a long-time experience with it. Will revise later.
