When people sing praises about the R4i, you might be wondering as to whether or not it is something that is worth upgrading to. If you look at all the options that are present like DSTTi, EZVi, AK2I etc. Hence, it can get quite perplexing in the end and you might be thoroughly confused as to whether or not you should go in for one kind over the other. The good news is that the older DS owners have no option but to stick with the R4i, as none of the other options are going to work with their console in any case. 
Hence, if you own a regular DS, don’t think twice about and simply go in for the upgrade. The superior features with the new generation card are definitely worthy of being upgraded to. In fact, the oodles of space that the new format allows you to use is something that you are bound to find advantageous. Consequently, you might want to think twice before deciding to stick with the older format. However, if you plan to trade in your console for a newer one, then it might make sense to simply wait and buy something else, not necessarily the R4 SDHC.
Watch out for fakes, as a number of users have managed to buy counterfeit versions of the R4 SDHC. These things are extremely dangerous and capable of ruining your console, if you don’t take care while purchasing them. This is something that you should ideally avoid, as it can get you into a lot of problem otherwise.
