Isn't the size of the Jornada about the same or even larger than the Axim?
I find it interesting that you're not holding out for PPC2003. Is it because the features aren't that appealing? Or is it you believe that current devices will be upgradable? Or perhaps you believe you'd have to wait too long?
What makes you think the H1910 will eventually sport the new PXA255? Of all the current PXA250 devices only the Dell supposedly has the new processor, but that seems to be nothing more than a rumour. I have asked a couple of times wether it is true but I didn't get answers. I personally worry that HP will just stop producing the 3900 series and introduce a new series with the PXA255. It appears to me that HP Canada is trying very hard to rid itself of its 3900s. It offered $50 and $100 off of the 3950 and 3970 respectively for the month of February (free shipping as well). Then it extended the offer to the end of March. Now it is April and in addition to the discounts, they are offering a 64MB SD card for $74, which is $75 off of the price normally listed on HP's website. I know that you can get them much cheaper elsewhere but an uninformed buyer may not know this. They say the offer ends on April 30, but I seriously doubt this considering how long they've had this promotion already.
I don't know. I bought my H3630 half a month before they announced PPC2002 so I'm still a bit sour. If I'm holding out with a H3630 I can't see why you can't hold out with both a Jornada and a Dell. I have to admit that I'm basing all of this on a lot of assumptions.
Just my 2 cents.
