30GB Hardrive in a PDA - the Tinnos

Akihabara News has posted pictures of a PDA from the Korean company Tinnos that features a massive 30GB hardrive. My question would be - why on earth would you need that?! On top of the huge memory there is a 4.3″ widescreen TFT, a camera, MP3 player and Windows Mobile 5.0 OS. No integrated phone or anything incredibly exciting beyond the hardrive the size of Jupiter. I just can’t think of what you’d possibly store on it. Suggestions of 20 videos, 5000 music tracks or 20,000 photos just don’t seem entirely plausible. By the time you transferred them all over, you’d be ready to change it for a newer model. If you’re looking at the spec and going “wow this is exactly what I need!” stick up a comment to let me know why and what you’d want to use it for. The model will be on sale in Japan from June, so it’d have to be worth the trip as well!
