Finally got round to exchanging my high-res MacBook Pro to the standard res. I had used the same hard drive, so just swapped it in. My eyes.. so much more relaxed! I know this seems like a backwards step, but I think it'll be a few more years before websites are designed with such high PPI displays in mind. Don't get me wrong, it was good being able to have so many windows open, and have so much desktop space, but I just found my eyes were tired/strained a bit from everything being shrunk down.
