Nobody asked for my opinion, but I'll give it anyway. Feel free to skip it if you don't like reading novels. Also, apologies in advance if I offend anybody.
I'm a long-time Arch user (on and off), and although my daily-use machines run OS X and Win7, Arch has always been my favourite distribution. Despite the fact that I've been away from Linux for a while, when I got my Pi and I was trying out Raspbian, my first instinct when I ran into trouble was to install Arch—and, lo and behold, the issues I was having with Raspbian don't exist in Arch. For me, even though I'm not a power user, Arch solved my problems, and I feel comfortable in Arch.
If I had another Linux machine, or another miniSD card, or if I wanted to bother going upstairs to get my MacBook (I'm in a wheelchair), I could easily have followed the [awesome] instructions at
http://archlinuxarm.org/platforms/armv7/broadcom/raspberry-pi-2. It's not
hard to do it this way, by any means—but for me and a lot of others, having access to an img file is just more convenient. In a matter of minutes, I was able to download an image from
lomaster and jump right in again. Ignoring the fact that my MacBook was just upstairs, I had already waited a significant amount of time getting all of the pieces together so that I could enjoy my Pi, and I would have felt somewhat frustrated if I had to wait even longer because, say, I needed a second SD card on top of the one I got in my kit, or something like that.
Negating the need to follow the standard steps is not about lowering the intellectual barrier of entry; I don't think anyone is arguing that. Instead, it's lowering the barrier of entry for people who don't have a lot of extra equipment around (SD cards and such, or an extra computer running Linux) and just want to get up and running, either because they already know about Arch's reputation and they want to use it as a learning opportunity, or just because they prefer it... maybe the Pi is their only computer. I'm on a disability pension, and I blew a good chunk of my money this month on a Pi2 kit, a new monitor, peripherals, etc. I'd love to have the ability to play with a bunch of different OSes at once, but I don't. My decision to move to Arch was not taken lightly, but having access to an img file saved me a lot of grief. Thanks,
lomaster (Like someone else said, I don't know about the politics that led to the decision to drop img files. In my case, it's just that I can very much see the use of having them around. If I had more technical knowledge, I would help host them.)
