I loved Borland's tools. But they got Microsofted just like dozens of other apps, one by one over the years (word proc, spreadsheet, browser, etc.)
And Borland sure did their part. There were a number of great products they acquired and then destroyed. The Brief editor is a near and dear example for us developers, but they also went out of their way, it seems, to destroy dBase and the whole Ashton Tate thing. And Sidekick was a really cool app that they managed not to handle well, too.
