Summary: Personal Experience I've had this unit for over a year, and I've been suprised at the way logarithmic brightness actually works; this projector thows an image well even with enough light to read large print. With the obvious exception of text, I can easily get the image to match my laptop screen. Using this as a standalone slide projector is as painless as it gets if you use the included SD card and don't expect it to whip through large amounts of JPEG's.
Summary: If you're like me and always on the go, you would understand the value of having something portable that works. I'm really fond of the M1's size and because it has an aluminum housing, I'm not as worried about it when I travel. The unit is also very bright for its size. The only bummer is that it doesn't support MOV or PPT files but since I can connect my iPhone to it, I guess it's alright for the projector to not have those functions.
Summary: Personal Experience If any one of you have tried doing P90X at home, you know with some of the routines like Plyo and Cardio X, a living room sometimes is just not enough space. I ended up buying this projector so I could have some sort of display device in the garage where I do some of my workouts now. I found this projector relatively easy to setup. The menu did take a few minutes of getting use to but once you understand how it works, it's fairly straight-forward.
Summary: Personal Experience After seeing the first generation projectors, I was excited but skeptical at the same time. 10-15 lumens was really not going to cut so when i saw 75 lumens i almost jousted out of my computer chair!I had the opportunity to see one of my coworkers bring one of these to work.
Summary: I spent 3 months researching these micro projectors and found this was the most excellent on. I have it right now in my room at 78 inches and it is amazing. Best quality around 50 inches but light or dark, the 75 lumens keep it picture perfect!!
