I have a couple of comments to make as regards this article.
4) Flash drives have much utility as boot devices and for system recovery. Ever tried doing a net boot from a system with a dead boot drive? How about restoring your back up image to a new storage device? From the net? Days to weeks? Use a Flash drive to boot and remove malware or check the hardware to see what the problem is? A USB Flash drive makes these much easier and quicker than optical media and is capable of being updated.
5) I have and use on my daily walk an old Sandisk Sansa e260. This little very solid and well made device is a real treat to use with Rockbox firmware. The internal 4 GB is plenty but as it also has a micro SD slot I added an 8 GB slab. The device will need recharging every week or so as the internal gauge tells me it should run for 24 hours continuously. IDK but I do use daily. OH, yes the battery itself is user replaceable and they are widely available. The sound is as good as my head or earphones are capable of producing. Unless this thing dies outright due to hardware failure, I don't see myself without it. Oops, I have 2 of them.
7) Yup, the lowly besmirched home PC. As to being overpowered, I would agree. The attitude of AMD as regards their chips being 'fast enough' is indeed spot on for the average user. I am writing this on a desktop with a 4+ year old CPU, a 2+ year old GPU, dual monitors (and am capable of adding more), 2 USB hubs with 11 ports,plus the 8 on the motherboard, a wireless USB keyboard, USB camera, 2 eSATA ports with 2 drive docks attached that will run 3 drives between them and just for snits and giggles, a DVD drive. I haven't done much in the intervening 4 years beyond swapping the RAM for a faster bigger set and the video card. I haven't needed to as it all runs fine and does what I, the user, needs it to.
I support a community where I live and have gone from the position of 'needing' everyone else to have a bigger faster box to meeting needs. I rarely advise a CPU upgrade anymore as finding one that will work in whatever Joe Sixpack's home box can be problematic. I am finding that people can get along with older hardware that works versus shelling out actual cash money for a better experience.
9) A battery powered alarm clock will IME generally need to replace the AA or AAA cell every 2 years or so under normal day to day use. Just like wall clocks. I, too, am a cheap clock user, in that my clock cost me roughly $1, before batteries. My current no name absolutely cheap as in chicken bottom of the barrel OMG flat out low budget piece of crap alarm clock with its piercingly loud alarm (the main reason I chose it BTW) doesn't keep time well but in knowledge of this comes the solution( check and reset the time manually, zoot alors).
