As already reported by Ed Brill and others, this is, I think, truly high praise from Stephen O’Grady of RedMonk for the capabilities of Eclipse RCP:
Notes 8 client is, simply put, one of the nicer looking Eclipse RCP based clients I’ve seen to date, on par with what Microsoft is delivering in its quite attractive new Office release.
A question that I have heard several times over the past couple of months is along the lines of “…if I use RCP, will my application look like the Eclipse Java IDE?” The answer is clearly no, as the new products from Lotus are demonstrating. The team there have spent a lot of time and effort demonstrating that you can build very cool-looking applications with RCP.
