One huge advantage the iPod Touch/iPhone has over the DSi, at least as far as I can tell, is that downloaded software is not tied solely to the hardware it is downloaded to. That alone makes me not want a DSi. I can live without the GBA slot as long as they replace it with a virtual portable library. In fact I'd love that and consider it an improvement. However, if you can't play downloaded software on more then one DSi, that is truly a dealbreaker for me, and unfortunately all signs seem to indicate that they are taking the same approach that they took with the Wii.
Hopefully I'm wrong. Hopefully they are taking an approach similar to Apple's. Apple allows you to install downloaded software on up to 6 iPhones/iPod touches, and that includes running the software on all of them at the same time, even networked. If Nintendo does that, I will buy a DSi not only for myself, but I'll upgrade my kids to DSi's too... well... eventually.
I'm thinking they don't want this because they'd lose out to extra $$.
How often do people change systems? I often laugh at the guy that states I've had 4 wii's ... wtf.. why?
I've had mine shortly after launch and still haven't come up with an excuse to swap out systems since it still works fine. Maybe needing the money...
But going back to the DS...
The big N probably doesn't want what you just described. You pay $5 or even $10 for title and share to every DSi you have... up to 5... that's about $25-$50 difference... or a loss of about 80%.
I really don't think Nintendo would even want to have that feature.
This is probably tied to pirating software too, they are huge on making sure none of that happens, and this would be a way to make sure they get max profit.
I too would glad to re-download... but then I have to think, why would I have to... only if I either break, or lose my system. Selling it or getting a new color isn't a big enough reason to nintendo in either way.
I really would like that freedom though.
Makes me wonder where all this information is going, on the internal memory or the SD? eventually it'll be hacked.
