Why wasn't the PSP vs. DS a repeat of the PS1 vs N64?

It took a while at first but Nintendo marketed the hell of the DS (especially with DS Lite and Wii) and they really made it clear that anyone could play it. When did anyone before that try to sell gaming to grandparents or what we now call boomers? I don't think it had been done before but Nintendo really made the uniqueness of the DS stand out and made quality games that appealed to different people, I remember Brain Training used to be huge and many 3rd party games came out that used the dual screens and stylus. It wasn't very powerful for the time but still appealed to traditional gamers as well as Nintendo's 1st party was always strong on handheld titles. Pokemon was still huge at the time of DS too, those games are getting very expensive now. The DS (unlike the 3DS at launch) was also very affordable, I remember it cost £99.99 for many years, imagine getting a system at this price now! Also in a way the success of the Wii made the DS even more successful.

I grew up on the PSP and it pretty much got me back into gaming as a teenager but the games as awesome as they were smaller versions of what were on the PS2, they were fewer new IPs on PSP than DS, many PSP games were designed to be played for hours at a time rather the bitesized DS games. I hate to say it but the DS was the better system, much stronger battery life and more portable, UMDs were cool for the time but not ideal for a handheld. But given Nintendo's dominance in handhelds basically since the original Game Boy, the PSP still was a valiant effort. The PSP sold more than the 3DS.
