Hello.. That's a really interesting question. I have been wondering about the same for quite some time. There has not been much work over WSN at our place. So when I began with my project a couple of months back, I started with tinyos-1.x as a few people who had worked over WSN suggested using it, saying I would get some help from their experience.
We have micaz motes at our college.And as far as I know these support tinyos-1.x. Please correct me if I am wrong. It was only when I joined tinyos mailing list, thanks to the people here I realized I am using an obsolete thing, I have upgraded to tinyos-1.15 and also installed tinyos-2.x using VMWare player. We are also working over getting Iris motes soon. But I have been asked to work mainly over simulation work and that too with GUI, since tinyos-2.x doesnt have something equivalent to tinyviz my chances of switching over to 2.x faded away soon. Or is it still suggested to use tinyos-2.x considering my work requirements? I am glad that despite people not using 1.x much now, I found some people who have been very supportive and helped me carry on. I owe a lot to people here. I really appreciate your concern to ask these questions. And I am all open to suggestions from you/others. Thanks...
