Since the start of 2009, search engines were flooded with requests looking for Nintendo DSi reviews. This indicates that many people are on the fence with regards to purchasing Nintendo's newest handheld. There are a number of pressing reasons for this need for Nintendo DSi review.

- Many people are worried that the DSi is just a marginal upgrade over the last 2 incarnations, the DS and the DS Lite.
- Many people are wondering whether or not the new features of the Nintendo DSi warrant the $169.99 SRP attached to a unit.
- Many people are wondering whether or not the DSi is the last upgrade to this generation of Nintendo portable systems.

Here's the deal that almost all DSi reviews will tell you: the DSi is not a revolution in the portable gaming industry, it is an evolution of an existing product that many people are already using.

A Nintendo DSi review will not be complete without mentioning the features that the DSi possesses. These are:

- Sexier, more lightweight design that's 12% less heavier than the DS Lite.
- Dual cam integration, with each cam having 0.3 megapixels.
- Improved audio features that can rival the best MP3 players in the market.
- Improved online features such as a dedicated DSi Store and better connectivity to the internet.
- External storage device in the form of an SD card slot.
- Additional level of brightness with more optimized battery consumption for high brightness settings.

However, a DSi review will also be incomplete without mentioning the drawbacks of a DSi unit. These are:

- Lack of physical backwards compatibility with Gameboy and Gameboy Advance games because of the exclusion of the GBA slot.
- Peripherals that are attached via the aforementioned GBA slot - such as the guitar pad for Guitar Hero Mobile and the DS Rumble Pack - are rendered obsolete.
- Battery life, though optimized, wasn't extended by that much.
- The DSi is still, in essence, the same as the very first Nintendo DS that was released.

The conclusion for this Nintendo DSi review? In a nutshell, the following rules should be observed:

1. If you already have a Nintendo DS or a Nintendo DS Lite, then you don't have to purchase the Nintendo DSi. The Nintendo DSi is not a new machine. It is just an upgraded version of older models in this Nintendo product line.
2. If you don't have a Nintendo DS or a Nintendo DS Lite, then the Nintendo DSi is the best handheld for you. It may cost a little more, but the additional features - being the logical evolutionary steps that they are - will ensure that such a system will last longer than the previous models.
