So, my Dell laptop has met it's maker after 4 years of reasonable use. It's time for me to buy a Powerbook or iBook (still undecided as to which one. I might hold off a little for the new 15" PB.) The question is: Where should I buy it? Options include: - My local apple store - apple.com - other websites like macwarehouse.com or smalldog.com - another retailer like circuit city or someone else What are the advantages/disadvantages to any of these options? It looks like extras like more memory are more expensive from apple.com than other retailers. Can I still take my laptop in to the apple store for repairs and such if I buy it from another retailer? Anything else I should know about?
