Useability is the key for handheld computers. It could be possible to stuff a
20Gb drive in it, but then with the current battery technology you could not use
it for more than an hour.
Then the handheld would be heavier, and after carrying it in your pocket for one
month you would probably reconsider the idea.
Anyway most handheld applications do not need that amount of storage.
Even 128Mb of storage space, which is possible with today components (DRAM or
Flash), would be far more than enough.
I guess that users would prefer having wireless access to the Internet, phone
capability, more battery life and a color screen rather than a hard disk.
The philosophy of developpement for handhelds is very different than for PC,
because resources are a real issue. If I had to develop a chess program for
handheld computers, I would simply forget about bitboards, big hash tables, big
opening books and TBs.
