I am looking at getting a DSi XL (for the bigger screen, mainly) and I have a few questions about it. 1. How does the anti-scratch protection on the bottom screen compare to the DS Lite? 2. How well does the web browser work? 3. Is it safe to use a stylus (Pen style) designed for the DS Lite? Yes, it is officially licensed. 4. What is the weight like? Is it comparable to the PSP? 5. What are the chances of getting a system that can be damaged by NesDS?
