It'll be nice when SSDs come down in price/GB. Should help make day-to-day work seem just a tad quicker.

I can't find good numbers, but it looks like SSD's are still around 0.1 millisecond's which is still 100,000 nanoseconds. And 1/1000th the access time of RAM if if they are 100 times faster than HDD's. Most people don't really notice that big of a jump from HDD to SSD's and, I don't see it being as much of an issue for a while due to the increasing ram and cache sizes.

  Some videos show that SSDs could improve experience in terms of booting, launch, etc: http://www.youtube.com/watch?v=pJMGAdpCLVg http://www.youtube.com/watch?v=pJMGAdpCLVg It's that kind of speedup I'd like to see -- disk-heavy tasks that don't peg the CPU.

  The major improvement coming from SSDs is that seek time no longer kills you. People will notice a difference going from random access on a rotational drive to random access on an SSD; sequential access, not so much.

    My point was while SSD seek time is 1/100th HDD seek time you don't get anywhere near that big a jump. Because, while a HDD might take 100x as long to get you the first bit, HDD and SSD take about the same amount of time to read the rest of 4kb the sector.

  SSDs vary a lot by write speed. Most today are slower than HDD for write throughput. (Intel's SSD drives are actually fast, but expensive.) This will get figured out and make a big difference. But still no comparison to RAM.

Moving to SSD is a very noticeable performance bump. In my personal experience it has been one of the better upgrades I've ever done. The performance gains are across the board whereas CPU/RAM upgrades these days only benefit you if there was a CPU/RAM bottleneck in the first place. If you happen to have a fairly good system to star with an SSD really opens things up.
