I think it's mostly historical ...
... in the "bad" old days, memory chips were expensive ... so if you'd bought a massive 256Mb memory card for hundreds of pounds, it was a real pain if your next camera used a different format card.
I remember the thrill of buying a 512Mb SD card from Jessops and getting the price down to £99 (wow!) but of course a 2Mp digital camera could get a fair few pics on 512Mb.
Now that the price of a 4Gb card is £10 or less, it's a lot less of an issue ...
... of course my laptop has an SD card slot (as does my DVD player at home) so I'd need to carry the microSD->SD adapter with me to make viewing/copying the images easy, but that's hardly much of a hassle, especially since one of my current SD card using devices is actually using a microSD card in the adapter as it was cheaper to buy it that way than a full size SD card.
I didn't read the full article, so I don't know, but if the front display works in video mode, then it makes the camera excellent for recording band rehearsals, solo music works etc. as you can look up and see what's in the camera's view :-)
