Photoshop or Gimp?

New Notebook

I have recently become the owner of an ultra portable netbook. I'm going to be taking it with me in order (I hope) to keep in touch while I'm travelling in England and around Sweden in the coming year. The screen image doesn't seem to have a great deal of colour depth - so i am not planning to use it to do a lot of photo editing, but I shall want to do some - so what programme to use?

Normally, I use Photoshop and normally I don't do much in the way of tweaking the pictures I take. Mostly I do some cropping, some contrast adjustments, some colour adjustments and I alter the size of the photos down to approximately 96dpi for Creative Commons licensed pictures.

Photoshop is expensive to run (legally) on another machine, so I thought I'd try Gimp, which is open source image editing and image creating software available from the GNU Image Manipulation Project here: http://www.gimp.org

So far I've not tested Gimp extensively, but the tests I have run simulate the sort of things I think I'm most likely to use the software for. Of the pics I've used Gimp for, I've posted three pictures to one of my blogs and one picture here to Ipernity.Now I've published these four, spliced with Photoshop processed versions of the same pictures.

See what you think!
