I have a 2 years old 13" macbook pro, and I admit I can't use my 6 months old PC when I just surf and code, since it's quite noisy and hot in the summer.
I still have a nice 20" flat monitor, and it'd be nice to use it, but Apple sells their adaptor 30 euros, isn't that a little bit expensive ? I'm reading this connector is not patented or licensed, do you think I can find cheaper ones ?
