Yes, flash memory storage is being used more and more widely and has big advantages over hard drives. It's silent, uses much less power and is less prone to mechanical failure. For now, though, it's a lot more expensive per megabyte and uncompressed music takes up a lot of space.
In the iPod line, all the units up to 64 Gb have flash memory but the biggest one, the 120 Gb Classic, still uses a hard drive.
