I could barely stand to get through the raving lunatic comments.<g> A lot of them were flat-out wrong, too, not just matters of opinion.
I was particularly amused by the ones who said you could build your own computer for less. As if people who are buying a $139 computer are likely to be building their own! Also, it's not true that you can build your own computer for less if we're at the low and middle end of the market. Compaq, Gateway, HP, eMachines, Acer are very difficult to beat on price at the low end. I know--the main reason I bought a new computer in January, 2006 instead of upgrading my older desktop was that I priced out everything and found that for what it would cost me for a new motherboard, CPU, HSF, and a gig of RAM I'd come out ahead by just buying a new machine. Plus if something wasn't working right, it wasn't my problem.<g> The street price of a new computer after rebates is often less than the suggested retail price by $300 or more. If someone is building it from scratch, there also is the cost of the case, power supply, and whatever you want to put in it that isn't built into the motherboard.
Building your own computer used to be a way to save money, but now the reasons for building your own include having complete control over what goes into it and having an intimate knowledge of its innards. You don't save money unless you're going toward the high end, where you *might*.
