Looking at the Sony's website, the only difference between the two is that the AR270 (the one with BluRay) has a faster processor and it is actually cheeper than the AR290. So to put it simply, no the AR290 is not worth the extra money. IMO, I wouldn't buy a laptop from Sony. They tend to be overpriced and there support is so-so. HP offers similar laptops with HD-DVD for less.
