By no means am I attempting to brag, but... When I realized there'd never come a day when we'd see 15K RPM drives in a laptop, we jumped ship from the 5.4K and 7.2K spindles to SSD...never once regretted that and never once looked back. :0)
That decision was easy, even with the huge increase in cost and the huge decrease in size. The most painful part was, during the transition phase, jumping back and forth between supporting newer devices with SSDs and older ones with spindle drives. Now, it's a distant memory.
Oh, the way things were...audio driver installed via 1-3 floppy disks against a 4.2K HDD. And the way things are now...600MB download and 3-5min installation time (not including the suggested system restart), just to produce sound!?!?! CARAZAY!
