HTC clearly is not stopping with the HTC Flyer which in itself is expected to start shipping any day now. Instead, the smartphone maker is currently engaged in the development of at least two more tablets which it hopes to release towards the middle of this year. Also, a good thing with the upcoming tablets is that those will come pre-loaded with Android 3.0 Honeycomb right from day one. The current HTC Flyer runs Android 2.3 Gingerbread but will be provided with the Honeycomb update soon.
As for the 7 inch Flyer, the tablet is expected to be launched in early April if not in late March though initial volumes are likely to be extremely limited. However, production will start off in full swing by May this year which is when HTC is expected to sort out all outstanding issues that is currently hampering the production process.
