I'm going to purchase CS5, for which I will use Photoshop and InDesign only. Here's the thing- I will also be LEARNING to use Photoshop and InDesign, and while I'm VERY familiar with the PC, I have never used a MAC except in the store to play around a little. I will be scanning and assembling 100 page brochure type booklets, both photos and text, a lot of scanning photos in, also digital photos from my camera, etc... and I will be doing this a good bit over the next couple of years. Assuming I have a comparable Dell XPS desktop & screen spec-wise to the best iMac, which is better to use CS5 on...? MAC or PC? (I know it's an age-old question) and if it's MAC, is it enough of an advantage for me to go learn to use the MAC as well as to learn the PS & ID programs? I realize that PC is more performance per $. But without factoring in $, I'm only looking for the ease of use and also speed comparisons, and would consider the extra cost an investment. A lot of comparisons across the internet have the issue I'm concerned about diluted because price comparisons are brought into the mix. Alot of the advice on this forum seems to be remarkably un-biased compared to what I expected while searching for similar posts, so I will value your input. Thanks in advance!
