Are the screens on the micro better than the screens on the 101 model GBA?
Higher PPI - crisper, clearer image.
...but the screen is smaller by far. Going from my Micro to my SP 101 is the equivalent of going from a DSi to a DSi XL. The main issue with the Micro's screen is that on a pure black image, there's a small about of noise (has been on all three micro's I've owned). Same as say, the Vita screen on black. The SP 101 doesn't have this.
I'm inclined to say the SP screen is better - but that might just be my preference.
EDIT:
I'm kinda planning to sell my green Micro. Yeah. It's mint condition, boxed. Got one dead pixel, been there since I got it - but other than that, it's mint. If anyone wanted, I'd supply an EZ Flash IV too for a separate price (obviously I'd delete all my games off first, but I'd put the client software onto the SD card). Bear in mind I live in the UK - sorry, US guys.
If anyone has a price they'd be willing to offer, PM me. Images:
