I still don't get why the iPod Touch uses flash and not a hard drive!!!
There are several reasons for that actually :
- overall smaller form factor due to thinner HD space
- faster read/write access
- longer lasting/more durable
- better shock-proof than a traditional spin up drive
Plus, SSD is really the way of the future, essentially. The only sad part is that the space is a bit limiting now, but once that clears out in (imo) 1-2 years....I'm sure we'll be seeing 200+ Gb of solid state drives on the market, most likely also in the future iPods. Unless your a hardcore music junkie, then I would assume 16Gb to be more than enough for music, and a few videos (which includes podcasts). I myself have 3,000 songs, and it barely even scratches the 7Gb limit for music on my (now obsolete by 9 days ) 5.5G 30Gb iPod.
