I questioned Tibbo about the availability of WIFI on the EM500, they advised;

Dear Lester, The WiFi feature for the EM500 is ready and we will release it soon. The WiFi and flash Disk will be available for the customers and the related documentation will be published on our website. We will announce this news by the newsletter once we release, kindly inform your customer to register at www.tibbo.com so that they can receive the newsletter once we release any new features or products.
To that i responded:
I'm sure that they will ask, "when is soon", as some customers say they have been waiting for some time already.

It is probably better to sell the product on the basis of functionality that IS available. with a road map showing planned development. That way the customer is always pleased to get NEW functionality not disappointed with a broken promise. Just an idea !
I really don't have any issues with Tibbo, they produce nice products that work. However i can see that some people want everything NOW and Tibbo are a little too forward in promoting planned functionality. Maybe they need a reality filter between the development engineering staff and the marketeers !

Never the less, as with our beloved PBP and many of todays leading edge products...everything comes to those who wait.
