I was really excited when I heard the iPhone 4 was equipped with a ~320ppi screen. Numerous smartphones already boast 200+ppi screens (and there are a few other products out there with 300+), but it's a fantastic achievement nonetheless as far as typography is concerned.

I just wish it had been done with a reflective screen. E-Ink has demonstrated a contrast increase with their signature product, but I really hope that as EPDs and other e-paper technologies evolve, they become capable of supporting very high resolutions. I can't wait until the day I can read super-crisp text on a low-power reflective screen, as if I were looking at a printed page. I don't know if that's 6 months or 6 years away, but it's something to look forward to.

Unfortunately I don't have a 200ppi 5-inch reader or a 300ppi LCD to add to this snapshot, but I thought it was interesting. Each picture represents an identical area a little over 5mm wide on a page. They're not perfect pictures, but they make a handy comparison nonetheless.
