Just because something was successful does not mean that it couldn't have been even better, I don't see how this is an unfathomable prospect. The system was very well-designed, it was well-marketed and the dual screen combination sold it well. That said, I think that with more horsepower under the hood, it would be able to accomodate even better games. Again, I'm not criticizing the system from a commercial standpoint - it sold very well and it made massive profits since the hardware wasn't all that elaborate and I can imagine that the profit margin was substantial - what I'm saying is that it could've been a much better gaming system, which is an entirely different matter.Let me make things this way:
If you could go back in time, assume as Nintendo CEO and had the option to release DS is, or more powerful the way you, as a consumer wanted,
what would you do? Since DS made such huge success and had plenty third party support, it can be said it was right to release it the way it is,
from the point of view of marketing. You can keep criticizing DS for been underpowered as long as you want, but I doubt you would have done defferent,
only a fool would trade the certain success of DS for having a somewhat better system.
Having experienced both the DS and the PSP I often used to say that "if the DS and the PSP had a baby, it would probably be the best handheld in the universe" and I maintain that statement. The DS was lacking in a variety of areas - it came with no web browser, online store, multimedia features, camera or external storage until the DSi line came along, no analog stick, rather poor hardware specs (4MB Shared RAM? Really?) and it wasn't wide screen, which was a bit of a shame.
As most things in life, hardware is all about striking a balance. In the case of consoles, it's the balance between specs/features and the overall price tag. In my opinion, neither the DS nor the PSP really struck that balance. The PSP was the "over-engineered, expensive handheld" and the DS was the "under-engineered, affordable" - the former was met with moderate success, the latter spread like wildfire, but I maintain that something in-between of those two would've been ideal.
