Gosh, no. They already have a big monopoly-to-be, don't let it grow even more. I don't like when enterprises grow too strong to control all the data we move from one computer to the next. Nobody should be able to concentrate a similar amount of power under a single head. And much less if closed source products are involved, cause then we only get total obscurity about what's being done with our personal info.
I used to run Opera years ago and got away from it. I'll have to say this newest version is lightening fast and easy to use. Maybe Google should have bought Opera rather than creating Chrome (also fast in Windows...)
