I am an American and I have been using the z10 here on T-Mobile USA for the last three weeks. I have posted my feedback and opinions of the device and my user experiences on most of the CB z10 forums. I also feel the device will do well here. I was just in a T-Mobile store and showed my shiny new z10 to the sales staff and they where amazed and excited. I took the time to explain the great features i.e. BB Hub, BB Flow and Gesturing. and they played with it and all they said was "wow".
There where also a couple of other folks in the store that showed some interest, one of them also pointed out he had read some of the negative reviews from you know who and now that he had a chance to touch it and have someone knowledgeable to answer his specific questions, he is seriously considering buying one when it's launched here.
Being a GMail user, I also showed the group how much the GMail interface has improved over the older Blackberrys and the Google Android users where excited about that. I pointed out how all their birthdays in the Calendar where synced, both from Google and Facebook etc. I spent a good 45 minutes, but it was worth it knowing there where future Blackberry customers. Mission accomplished.
I have felt like a Blackberry ambassador the last couple of weeks, but I honestly think that is how the device is going to have to be marketed here, the user experience. Not some crappy demo that hinders the users ability to see what the device is capable of. You have to get the device into their hands and have a sales staff that is knowledgeable enough to explain the new OS and device features. Just my input, in the end, the customer will make his/her own decision.
To all my fellow Blackberry users out there, I drifted away for a few years and I was seduced by the Apple and Android devices like allot of folks where. I had lost faith in RIM for not getting devices that the consumer wanted to market, but with the z10, I can now honestly say, I am back.
