And now you telling me that flash technology is too big for mp3 phones and digital cameras ... 90% of a smartcard or flash pendrive is only plastic garbage meat. The real thing, the silicon chips, is really very small from almost the beginning ... really ...
Flash memory silicon chips are small but their capacities and interfaces have gone through enormous changes in the last five or so years. As have processors and memory and even hard disks. It comes down to researching what you want, ensuring it meets your standards. Then buying. I agree there are some manufacturers of equipment/devices who try to tie that equipment to their own revenue streams. Apple springs to mind. But it is down to you as an informed consumer to make those choices.
P.S. Don't ever try changing the cam belt on a Citroen.
You can draw parallels quite easily with the bolt/nut industry. but how many different sizes of nut and bolt are there?
but i see a rationale for this many size variants! you need to carry different stress load by different sizes! what is the rationale for so many form factor of smartcard!? Especially if interface is defined by open standards? Why is this 1 mm long? And this 0.02 mm higher? Why the pin can't fit even the number is the same? Is technology that constrain it to be so? Try to open the plastic meat and see how tinny is really. What you see? This size variations has no rational purpose
i see only one, like is in usb connectors, when you want to connect to different size devices, and some of it need also to be powered by usb connector. Also you can have here different formfactor when you want to fit for different size devices. But for all digital camera, with almost same size, i see no rationale to be so many incompatible smartcards!
you can't just go and buy any combination and expect them to work together. You also have different types of bolt. Flat head, Phillips head, grub, star, and hex, plus too numerous to mention. These are all made by different manufacturers some of the designs are open and implemented widely, others are (believe it or not) proprietary.
I see a valuable point here. You hit me, really ... I see a lot of gates also ;-p ... Like the cam belt of a Citroen ...
Try changing the cam-belt on a Citroen with a standard set of tools.
i am a smart guy, so i don't like futile battle, with no chance to win. I don't do it ..
Over time technology gets better (generally) and designs have to change to accommodate new features. Cassette tapes were replaced by CD's which are being replaced by DVD's and now HDDVD and BLUray. With a technology as fast paced as flash memory the changes are quicker.
This a good argument for the muddy situation you see right now. Technology is changing so quick that make you head to spin! But also i see no effort from smartcard manufacturers to try a more compatible approach, for example my newer smartcard carrying a wicked technology to be able to fit to the same formfactor and pins from a older smartcard. And all device manufacturers is so happy to not be compatible
. So now i want that super digital camera with 20 megapixels! i have already a 512 MiB, xd-smartcard, i don't want to buy another! Why don't fit to this new device!? I see no rationale for this situation, only the gates, and the happy gatekeepers !!!
The fact that you can buy a card reader which will accept all major types of flash card is testament to the open standards involved in their design though.
when this compatibility flash card reader have also only one hole, or holes classified by size only, i will understand the value of this open standards ...
You could if you wished manufacture such a device without having to pay royalties to the card manufacturer. In fact you could manufacture the cards themselves in whatever format you wished without having to pay royalties either.
you see here the problem? If my can do that, why manufacturers can't do that!? Why so many incompatible pins!? And form factors? No rationale, because myself can do it!
In many ways its like Linux distros, there are hundreds of them and they all have their incompatibilities and peculiarities but each is open and you can if you wish implement one of your own as your needs see fit.
hmmm ... but you don't buy it not so? In this situation that little license, telling you that this thing do not carry any warranty, for any purpose means something, and this is exactly that: you don't buy it so i have no legal obligation, as a vendor, to you
!!! You test and use it if you can. But with no obligation, and this if fine for many of us ...
But you buy the damn smartcard and the damn digital camera !!! They have some form of obligation to you! And one of it is to not try to overprice you with artificial technological barriers .. i hope ... or i am too naive here !?
