The Nintendo DS has become the best selling games console in the UK with over 10 million sold.It take the crown from Sony's PlayStation2 that's been on sale for over ten years!
The gaming device appeals to all ages and the Brain Training series of games has to take a lot of credit for its success. The DS was one of the first devices to have a touch screen and this allowed Nintendo to reduce the other controls thus simplifying the device.
Nintendo can't afford to relax as games on other mobile devices especially phones is making a severe dent in their game sales. With games on the iPhone free or starting at 99p. If you compare the same titles on both devices the iPhone games are generally a lot cheaper. Another advantage that the new phone have is the ability to download games (only recently introduced with the DSi).
With great exclusive titles like Professor Layton and Zelda Nintendo may still have the edge on the competition - for now!
