I'm going to treat myself to either a DS lite or DSi sometime this month. I'm really in doubt which one to get, both have their advantages and disadvantages to me. I'm gonna put em here, and please try to comment on my positive and negative points for either, since I will be basing my decision on them DS lite + Slot 1 2 (GBA) + No chance of flashcart-blocking update. + Homebrew (with extra RAM possible in slot1) - 4MB RAM - Not as good hardware as DSi (touchscreens, smaller screens, fewer RAM) DSi + Faster processor (133MHz vs 67MHz) + SD slot (great for homebrew) + 16MB RAM - No slot 1 2 (GBA) - Small chance of flashcart-blocking update. - No (DSi native) homebrew yet + DSi native homebrew has great potential (once possible) + The extra features like DSi shop, cameras etc. + Opera browser + Free 1000 points What I want to do with the DSlite/i is: - Play DS games - Play GBA games (important, but an alternative is to get a cheap GBA flashcart for my old GBA) - Use homebrew (very important to me) What is kinda boils down to is this: DSi has no slot 1 2 and no DSi homebrew yet. DSlite has a slot 1 2 (for GBA games and RAM expansion) and a blooming homebrew scene. Conclusion If I had to buy one right now I would go for the DSlite + M3 Perfect pack. And that's because the DSi has no homebrew capability yet.
