Deal breaker for me. Someone asked if the previous devices didn't have host mode would we have cared. Yes, this was one of the main reasons I bought the n800, there are actually ipaqs that have host mode, and for a good reason, a certain market absolutely needs it.

When I was looking at pocketable devices, my main concerns were at least 640x 480 resolution, decent screen size(3.5" or larger), and host mode or CF slot(there are CF ethernet and serial devices) or both. There are some ipaqs that have host mode and CF, but the combination of Linux, 800x480 and usb host mode, won me over and I bought a n800. If the n800 wasn't capable of host mode, I would have never bought the device, as it was critical for me. Us techies need easy wired ethernet and serial, anything without this is a deal breaker for us, because then we have to carry a notebook/netbook and then we might as well stick with a cheap phone we can use as a BT modem, because we will literally have to lug around a notebook everywhere we go, for the ethernet and serial ports, so we might as well run our apps on the notebook and not the phone.

What's stupid about this, is that it seems like nokia could have released two devices that fit both markets, it's what nokia is good at, making a range of devices to fit as many user types. Why not release two devices, the n900 and also a larger screened version of the n900 with usb host and maybe an external SD slot, to keep your techie evangelists and often developer crowd happy. It might not sell as well as the smaller n900, but would probably sell as well as the previous n800/n810, but those people are more likely to give back than the average user, so it's no big deal.
