Thats true, and I'm sympathetic, but think of it from Apple's perspective. The Mini is their tool for luring PC users into the Mac world. Like it or not, they're counting on word of mouth from switchers to encourage more switchers. If these ex-PC users are all saying "The OS is kind of nice, but the box runs like a dog and I can't do anything," is that useful to Apple? Apple's at a critical juncture right now where they have the better OS by wide margin (that margin will shrink with Longhorn) and they're readying an agressive strategy to take a chunk out of Microsoft's dominance. The focus has to be on appeasing these new disciples, or their friends will never switch and Apple will go on as the 2.5% market share underdog. If they divert any resources from the Mini to the iBook, they're making a mistake.
I speak as a PC power user who switched 2 months ago to the iMac. I wasn't willing to switch to the Rev. A iMac because it wasn't capable. The Mini was just a joke to me. Specifically, it took the iMac's new Radeon 9600 chip to convince me that Apple was serious. No knowledgeable PC user will switch to the Mini while it still has the 32MB 5200 chip and a 4200 RPM disk (I have no sympathy for people who can't upgrade the RAM themselves and sell the old stick on eBay). Those two specs are a major step back from anything used in modern PCs, and are absolutely not future capable.
Finally, one notable feature that I feel should be included without question - the built in Airport and Bluetooth should be in every Apple base model. They'll lower per unit costs by creating an economy of scale, ease maintenance by making all the systems similar, and create a new world order for all Apple users... something very cool that is standard on every Mac and virtually absent from the PC world. If they really want to get a "one up" on Microsoft, install Salling Clicker on all those Macs so iTunes automatically pauses the first time a switcher's BT phone rings... THAT will start a grapevine frenzy.
Sorry for the long post.
