Hello,
I propose to add a new functionality MapInfo TAB import/export, which should be available already in ArcView license level (similarly like different CAD data formats support). At the moment it`s possible only with ArcGIS Data Interoperability extension. Data East`s TAB Reader does not support export to MapInfo formats at all. ArcView customer has only MIF to Shapefile functionality.
It is still very urgent topic in Estonia (local municipalities, planning companies) and probably on the other countries, where MapInfo is widely spread.
Pitney Bowes MapInfo Professional has practical Universal Translator (UT) for spatial data interchange, but if to use Shape files generated by UT, there can be complications related to polygon objects/topology etc.
