Titled "What The Dell?" - here's an interesting blog entry on how hard it is to buy a Dell from DELL.COM.
Even though there is a little lack of creativity in the title [how many times has that been used?] this blog has a great perspective on buying an All In One from the two rivals.
Buying A Dell ... or not
I do question the author's process a bit though.
He apparently was already signed up for "one click" - something that you must register for if you have never purchased from Amazon or Apple before. This adds a lengthy step to any purchase from the Apple Store.
Personally, I have an extra step to all of my purchases from Apple because I use MYPOINTS ... which can also be used for DELL as well. [Saves me about 2%]
