Windows Geek, you forgot much better performance in that list
I use and swear by SSDs for the system responsiveness. Explorer loads faster, modern systems can boot within as little as 20 seconds, and application load times are often halved if not better. SSD's certainly are expensive, but people used to pay more than $1 per GB for 10,000RPM Raptor hard drives too just a few years ago... and that was for a marginally more responsive system. Storage has long been the slowest part of a computer system, and while this is still the case with SSDs, they have made exponential leaps in performance in this area compared to a regular hard drive.
As for WD's laptop 1TB hard drive, it's good to see the areal density catching up with the desktop models. But I personally see no use for it... I don't store data on my laptop and never will, anything over the first 100GB would never be used. I'd already use an SSD in my laptop except it's a pretty old beast with an IDE interface. Given a laptop gets tossed around pretty well during travel or even regular use, keeping anything stored on laptop just seems like a bad idea.
