Well, having gone through alot of trouble trying to get a DSi, I hoped it would be worth it. And it defineately was! The problem I always had with the old versions of the DS was that it was just a games console, nothing else, it jus played games. That's why I spent time trying to find games that were like tools (e.g.the web browser game you could buy). But the DSi has met my expectations.
It's cameras may be low res, but do we expect them to be 10 megapixel super cameras? No, they're just for fun, and that's what some people are finding hard to grasp, the DSi is for enjoyment.
The DSiware was slow to load most of the time, as was the bowser, but it was very useful for good games like Wario snapped or apps lke Flipnote Studio. A problem I found though was that you couldn't link your WiiWare account with your DSiware account, so you had to buy separate points, but this won't be a problem for people who don't own a Wii.
I was dissapointed by the internet, as it didn't use a 3G connection or special Nintendo hotspot connection, but an extra cost would probably be added if this was the case. On the other hand, the wi-fi is easy to use if you are connecting to a free hotspot like McDonalds and your wi-fi at home is also simple to log on to, you can get surfing in a couple of minutes.
Overall, this is a brilliant update from the previous DS's, and next up will probaby be a DS with video recording and software for it. But this is perfect for me, being just 11 years old and just wanting to play around with photos and sounds for fun. Well Done Nintendo!
