I guess you have not used current day laptops. I've used several brands that come standard with dual-core processors, 4 gig RAM, and 250 GB disks. Later this year, they are showing off mobile quad core laptops. The limiting factor on boot time and data movement is always the darn HDD, spining at a fixed 7200rpm. Using "parallel-channel" flash SSDs will indeed improve performance significantly, and when I can get my hands on one, I'd be happy to show you numbers and price data. I've been installing and testing OS's on various SSDs and CF devices that are single channel (300x speed equiv for CF marketing), and I can't wait to test the new parallel channel devices. But in so far as zfs server storage array with heavy write operations? Yeah, we'd have to talk "write data volumes over time" vs. device life span. But that is also set to change, as the vendors are working on newer flash tech that can last much longer. I still see many applications where an SSD or Flash can improve storage system performance in the enterprise. Just stay tuned.
