I sure see that the computer has improvements, but a lot of the features presented above are already in the ix3m v1 : Very good compass, oxygen analyser, super-readable display.
It some of the features are the same but there is a quite a bit of "upgrades" in the new version including the menu, buttons, display colors and screen, computer external case, algorithms, etc. AND there is also internal components and design changes that aren't apparent to the end user. The internal enhancements increase the reliability of their computers even more.
The price "increase" is relevant information.
What price increase? There isn't.
For owners of the existing model: How much difference is there really ? Is it worth the upgrade ?
That's a good question for them but I doubt that many would just throw away their older version just to upgrade to the new version. Some would want to have the latest and the greatest but many others won't since there wasn't anything "wrong" with the older version. I don't see your point here, you have none actually.
For new buyers : Same question . How much difference is there really ? Should I buy the new one of just pick up the older, cheaper version ? (a lot of the same functionality in a less fancy housing )
I am not sure that the older version will continue to be available as the older stock is depleted. Some will opt for the older version to save money and others will want the latest version with the enhancements/upgrades (myself I always buy the latest version even if it costs more money).
As you pointed out yourself. The ix3m v1 is already a great computer with a lot of features and still available for a very neat price.
Yes, until the current stock is depleted and there is no more of it available. If it were me buying for the first time, I'd go with the most current -BETTER- version for I see that the added features and enhancements are worth it for me.
You started off with false information (very in accurate information at best) and now back tracking. And yes, the older version is a great computer but the new one is a substantially better with very important enhancements and features. There are many more enhancements in the new version of Ratio's iX3M 2 than there is in the new Perdix 2 vs. Perdix 1. For some these enhancements matter but for others they may not but at the end the older version isn't going to be available anymore after their stock is depleted (I am not sure if it is still available from the manufacturer now actually).
FYI, although Ratio has plenty of parts stock for the next 12 months to manufacture the new computers, they are working very hard to keep up with the demand in their production. The reception of their new computers exceeded their expectations and are working very hard to keep up with the demand.
