Who said he should spend $3000? I think I offered some options that were 1/2 to a 1/3 that price. You can get an iBook starting at $700, an iMac from around $1000, and an eMac for $800. Just check out www.MacMall.com.
From Cdc's question I gathered that he might not have computer yet, so I offered up the Mac and its great, included software as an easy way to get the pictures from camera to website.
Cdc, as Albert Porter suggested, iPhoto which comes preinstalled on new Macs and is a great way to view and organize all your photos. You needn't buy the full professional version of Photoshop to manipulate, crop, color correct and resize your pictures. Adobe Photoshop Elements runs about 90 buckeroos and will probably do all that you want.
If you ever decide you want to make albums of your photos to share with friends or burn to DVD, Apple's new iLife is a $49 suite of mini apps that includes iPhoto, iDVD, iMovie and Garage Band. It's a great little package.
Boy, all you angry PC guys, what gives? If you read Cdc's original post he asked for nice people only. Notice how the PC guys like to brag about their Microsoft certification and de-bugging a C-whatever app. That's cool and all, but what does this have to with taking, editing and posting pictures on the web? At least a pro photog will have some helpful advice in this area.
Not to judge PC users in genenral, but if one were new to computers and read this thread, he or she might conclude...
Mac people = fun, creative and helpful
PC people = snobby, superior, grumpy, jealous, stiff and repressed.
Have fun Cdc researching computers and cameras like you would a new piece of audio gear for your system. As I said earlier, no matter the machine or that OS you end up with I'm sure you'll have lot's of fun.
Good luck!
