Dennis Howlett does some sleuthing around Microsoft's efforts around Great Plains, Navision et al.
If true, I hope Microsoft cleans it up. The middle market needs its stable support of these products and the VARs ecosystem that provide the implementation support - at much more reasonable costs compared to the systems integrators in the larger enterprise market.
Oracle could have a similar mess as it tries to rationalize multiple product lines and cutomer bases as I wrote here - and this was before the Siebel acquisition.
