So I did a dance competition two weekends ago. There were 880 dancers and I took about 40,000 photos. It was 5 days of standing on a aluminum sawhorse taking photos, next year I will get a platform to sit on. I switched my set up around, I bought 4 mac minis and 4 23" monitors since the laptop's screens sucked. I bought photo cart from www.picturespro.com and hosted it on my laptop so everyone could view my photos and have an online form instead of writing each image number down.
Everything worked great until my laptop died. Then I couldn't run any computers or edit photos.
I ended up buy a new Macbook Pro, found out I couldn't swap my old hard drive into my new laptop and that you need special pentalobe screwdriver to pull the cover off of a new Macbook pro.
Next on the list is to buy more MacMinis and monitors. Probably 4-8 of each. I am setting my enclosed trailer for people to view photos in during summer events, I would like to take baseball tournament photos this summer and maybe track and field.
