It seems like Intel has had less drama than other manufacturers. The only thing I remember "bad" was they "screwed" G1 owners out of TRIM.
I bought my Intel X-25M 80GB's back in March, and I'm certainly happy I didn't wait. Everything is fast now (except the Internet), and it's totally silent when it's actually being used like crazy (such as no Time Machine backup for a couple weeks--I have to check Activity Monitor to see that it's actually doing 284MB/sec of w/e). What's sad is that you get used to how fast it is, and then it doesn't feel fast anymore until you go back to a HDD machine... Then it's *GASP*
I guess if I was going to wait for something, the next Intel release would be interesting to see. But I wouldn't count on pricing going down unless the entire market goes down. Intel has kept their pricing despite the new products coming on board--and since I thought they had a superior overall product at their price/GB compared to the competition, I'm not surprised they have kept the price there.
And with respect to Intel's "slow" write performance--I don't have anything that can generate content at 80MB / sec, except for the SSDs themselves, and I'm not so lush with SSDs that I'm using them for backup
I bought two 80GB's and striped them mostly because it was the cheapest / GB among Intel SSDS ... and just a little bit for awesomeness in random IO ... Read/random read was most important to me, and I am quite satisfied.
