I came on forum to ask this same question. I have a 2006 iMac and 2007 MacBook Pro. About 6 months ago I bought a DSLR that has 32 megapixels. Downloading to either devices is troublesome. Takes forever, boots me out, etc. I took 180 images at a swim meet last weekend and it took almost 6 hours to download images and even then it double downloaded many images and I had to go back and delete them. I store my images on a 2TB external hard drive. One thing I definitely need is a disc burner. I'm constantly asked to take photos for other people and I burn the images for them. I don't have extreme vision issues however I am getting long in the tooth so a moderately larger screen would be nice. Right now I use my iMac for doing all my editing as I like having a mouse. I assume I could get used to editing on a laptop. I too would like to spend around $3,000 however could go a little more if need be. Thanks so much for this thread and all the good info/suggestions.
