Tell me this... aside from money issues.
Why wouldn\'t you want it?
No reason, none at all. A permanent storage bank... needed for online play... now tell me this, who here does not want online play?
The past add-ons were different. N64 Expansion pak.. not needed except for 2 games... Sega CD, who needed it, you got cartidges with the same graphics and games... you get the point, this add-on has purpose, and potential.
With the PS2 HDD, you can:
Practically unlimited storage space.
On-line capability(best part)
Download stuff right to PS2.
Get demos right of PS2(rumor)
Rent games off ps2(rumor)
So you see, if an add-on has a good purpose, and potential it will survive, and profit. Trust me, this is one of those must have things.
