The P2K is an iffy sale to me too. Don't get me wrong, the thing looks amazing, the LCD screens on the analog modules are a great idea(hint, hint, wink, wink), but when it comes down to it, the system limitations point me else where.
1.) 240 I/O points and that's it. No native I/O expansion.
2.) Connections, you buy the card and then you have to buy a separate connector? I'm not cheap, but that's a design nightmare. Real easy to order the wrong connector or not one at all and then start building a project and see, oh darn I'm held up for a 7 buck connector.
3.) Do-More can drop into an existing system, and use the stock of DL205 cards I have as spares.
Don't get me wrong, after looking over the offerings, the P2k looks to be a good value for the cost. For some new designs, I can actually see myself using it. Our Wire Drawing units would fit the bill. 64 I/O with analog. But after switching from a D250-2 to a Do-More, the ease of a major upgrade by just dropping in a new CPU far outweighs what the P2k can give me.
I also held off our system upgrades for a year just to use the Do-More after using the simulator and I can't wait to see the newest offering.
I don't see this as much as toe stepping as product evolution. The DL series is a good product but it shows it's age. The Do-More is it's fresher, younger sibling, but in the end there is only so much you can do with the base platform.
