well as a recent switcher ill chime in with my 2 cents. I had nothing but PCs for 10 years, but i was intrigues with all the software integraion that came with OS X. I plaed with the macs at the store whenever i was at the mall, and i had always wanted an iPod. So i bought an iPod video, and i loved it. I wanted an iMac for a few months, but then decided a macbook was better suited for my needs.
So i finally got the money saved up and bought one a wek after the santa rosa update. From the time i opened the box, turned it on, and was setup and online within 3 minutes, i knew i had made the right decision. I have never had emailing pictures, making websites, uploading albums be so easy to do. What used to be a chore i would avoid till i needed the files now is something i plug in and ODX does in the background.
Also, as soon s i turned it on, it found 3 different wireless networks around my home, one of them being a linksys, so no worries there
I have now had it three weeks, but it feels like i have lived with it forever. The only thing i worried about with the switch was playing WMP videos, since all my video files are that. I installed Flip4Mac, took about 5 seconds, and now all WMP files from my HD or the internet open in quicktime.
So all in all, no regrets switching. I just wish i could have switched sooner. Now, your needs are probably different than mine. I use my macbook for photo editing, sorting, website creation, music, internet, im dabbling in video editing, and mail. So far its handled everything ive thrown at it, but definately do your research, just like with any major purchase.
This is now the longest post ive ever done here.
