My work laptop (Dell D630) was frustratingly slow and an upgrade was still a year away, so I invested in my own SSD. I'm a little worried about the longevity since it's Windows XP and the company monitoring tools are always hitting the hard disk, but the performance boost is beautiful. Boot times fell from ~4:30 to ~1:30 and the system in much more responsive during everyday use. Here's a screenshot of Soluto's boot-time log -- the big drop in boot time is from installing the SSD (exact copy of the previous disk). Side note -- I love Soluto!
