Just wanted to say hi to everyone and I really enjoy the site. I have been searching the forums for a while and I finally bought my first Macbook. I purchased the Blackbook beacuse I am starting school and wanted to make the switch from a PC. My question is that I am looking to upgrade the HD of the Macbook to a 320 or 500 GB. I have read all the posts about the 320 drives and I was wondering if anyone has upgraded to a 500GB HD? Is the extra money worth it and is anyone finding any problems with the 500GB drives? Thanks again!
