What flaws do you see with the arduino?

What flaws do you see with the arduino and its "universe" (shields, modules, knockoffs, software &c)?

Although there are some that are quite apparent, such as the bizzare pin spacing, I'm sure there are some smaller issues that kept quiet.

I have nothing against the arduino, I think it's a wonderful little guy that's doing awesome things, and I'm really thankful it exists.

Thoughts?

Price. I have a freeduino that I got for $28 shipped, but the bluetooth ones are ridiculously expensive and there is no bluetooth shield.
I think to make the PCB design for a Bluetooth Shield.

Ok,let's start with a Bluesmirf and go on from there.Then have a connector for standard USB via Bluetooth.

The 3.3V supply provided on Diecimila and later versions is "weak." The 9V supply is "highly variable" (not there at all when powered by USB, and anywhere from 7 to 12+V depending on wall-wart.) The hardware is getting to be also sorta "highly variable", what with clones and a new "official" board every year or so. Official boards now span a 4x range of program memory size, for example (ATmega8 (8k) to ATmega328 (32k)) I don't find the add pin spacing to be an issue. See "Connector Conspiracy."

no too cheap : ( could use a couple heavy duty transistors should be covered/encased in epoxy, so that whatever you do, you can't ruin it

Donuts...hey, I forgot all about that ebook...money...I found a penny! :( My usb hub is not usb 2.0 and is therefore slowing me down when I plug things into it. Why do I have so much old computer junk? Oh, right, I hate to throw things away. Plus it is kinda cool, this junk. I mean it's just awesome. Plus I don't know anyone else who can say they have the guts of a 386 just lying around waiting to be awesomeified, not that it needs any more awesomeifization. Oh, you meant related thoughts? ;-P
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.

The new you is not you, and now what am I going to do with two awesome instruments of righteousness that are now obsolete?
I am me! D: They are not obsolete - far from it!

. What you call flaws, others may call features. ;) . As has been pointed out by gmoon, no controller is perfect for every application. . If I were going to play with general-purpose uCs, an Arduino would be high on the list - if for no other reason than the huge user base and support. . . I can't tell for sure from the pic (plus I'm no expert even if I could), but those all look like standard connectors to me. It would only make it more expensive to manufacture if they used non-standard parts.

I dunno, aren't all those knock-offs and variations attempts to address specific limitations? (aren't those pretty standard header pin spacings?) Any "dev board" is gonna be great for some applications, lousy for others...
