I'm just going to summarise my first thoughts about this article with the following short phrase:
Massive overreaction.
I'm sorry, Chris, but judging by the way you're going on the external battery is the size of a dinner-table. Have you seen the battery? Is it really that big and ... what was the term again ... cumbersome?
As one of the commenters on the original article stated - this is more a case of battery-tech not keeping up - the PS Vita is a tightly bundled monster, and it is going to draw a lot of power, and the users are going to end up paying the price for it. It's a sad reality.
The Kotaku article quoted in the comments listed about 5 hours of video playback (with lower screen settings) and about 9 hours of video playback. Personally, my gaming sessions on my PSP tend to be fairly short - 30 - 90 minutes at most, even when travelling, and the rest of the time is spent watching videos or listening to music. And assuming the clip-on battery is more or less normal sized, its not going to suddenly turn the PS Vita into a damn monster laptop.
Sure ... the PS Vita doesn't win on many counts - it's expensive, the spare battery will probably be pricey, accessories for the thing is also guaranteed to be expensive, and in the end the battery life isn't anything to write home about. But seriously, will the extra battery really be THAT much effort to carry around? A battery, and by extension a battery pack - it's kinda a small thing.
In closing, that entire article comes across as a total whining session - it's like you saw something worth complaining about and you went and hammered out an article of condensed nerd-rage without actually sitting down and thinking it through objectively. You're making a mountain out of a molehill - terrible article in my opinion. If that page had a dislike button, I'd be mashing it right now.
Oh wait ... Disqus has been implemented. Mashing away then ...
