I felt like I was reading this out of a magazine... and you want to hear me out Julio Franco? okay... <grin>
1. GPS - I vehemently disagree with this one. I have tried Google maps a few times in a bind and it works, no question about it. But it is slower on the initial calculation, slower on re-routing, inferior voice direction, than compared to my Garmin. Also mentioned in the article, needs both GPS and cellular service. You are also generally tying up your phone in order to do this. The only advantage Google maps and such services have is that they are better at finding newer places that have opened up or running searches for say, restaurants and don't know the name.
2. BD/DVD + Players and 4. Flash Drives - When you have quality stuck-ups like me streaming pretty much anything does not meet my expectation of quality. When you start loading 1080p video it can become fairly taxing to your connection, and heaven forbid you want to watch it again later and have to load the video back up. Plus I easily can't find over half of my DVD/BD collection on movie streaming services. I know first hand as I have frequently let people borrow my copies since they couldn't find it on Netflix. Even if I digitized it, I'd be committing piracy by sharing it (GASP) and it would require me getting it online in the first place. This brings me to flash drives. As mentioned by TomSEA, cloud storage is very impractical for copying and subsequently retrieving large amounts of data. More importantly, what if the computer in question is NOT connected to the internet (GASP again), is on a slow connection, or even worse have a low data cap? Considering the average broadband speeds not only in the US but in most countries, a USB 2.0 flash drive would almost be faster if not for physical transportation.
3. P&S Cameras and 8. Handheld Camcorders- I shoot with dSLRs so I don't care so much about either of these guys. Also, people have pretty much abandoned them for the convenience of cameras in smart phones, even I will whip out my phone for something quick and dirty because it is much easier. However the article makes the common mistake of suggesting having a larger megapixel count means better photos. The camera/smartphone's ability to process the image data to something meaningful is just as important, and there are 4 year old P&S cameras that still get better pictures than phones because of better processing. Many recent cameras also boast Geotagging and wireless upload, or in many cases can use wifi enabled SD cards so they offer similar capabilities, though the convenience factor is still not as high. Compared to picture taking, video recording is a far less common task which makes the importance of camcorders relegated to events you really REALLY want to keep. Like weddings or graduations...
5. MP3 Players - I will agree with this one to a degree. Phones have largely replaced standalone MP3 players, with the itunes/iphone combo making it incredibly simple to keep track of everything. The only real loss is battery life which MP3 players by and large excel at. If not actual music tracks many people simply stream music, again something the average MP3 player cannot do. Thinking about it makes me want to use my Samsung YP-K5, that thing was a beast. TomSEA has mentioned a good point though, working out is sweaty and gritty, and with all that movement and fluids fairly hazardous to one's expensive phone, and one of the few reasons I would immediately prefer the standalone player vs the phone.
6. Handheld Consoles - I am really sad to see them go on the wayside. The truth however is that people like free and cheap games. They can get them and toss them as they please. When the entry price for paid games are often under $5 on a phone or tablet, it makes it a lot easier to make an impulse buy than a $20-$40 game. Sure the handheld consoles are more powerful/efficient, but the audience is not only changing, but shrinking which is evident with the significant declines in sales for basically anything handheld console related.
7. Desktop Computers - I'll actually agree with this one with a major caveat: Touch only devices make poor production hardware. Over the years I have become proficient enough with typing on the screen to not look like an *****... but I will never be as fast as on a dedicated keyboard. This makes typing long documents or emails (or embarrassingly long replies to articles) error prone and time consuming. Tablets, since they were mentioned, do not nearly have the performance, or accessibility of at least mid range laptops. Barring very few exceptions, you'd not want to be doing any heavy production of content such as music, images/pictures, video editing, etc on a tablet, or depending on what you're actually doing, even on a laptop. For the bare minimum usage type which is mostly consumption, I can see where a tablet or just their phone would be enough for many people. For the rest, absolutely no way.
9. Alarm Clocks - Excuse me while I set my alarm clock to wake me up in a few hours. =) I think this one is basically nitpicking at this point. Also, it's nice to be able to see the time without having to find/turn on your phone.
tl;dr: wall-o-text, move along~
