hm...yeah...Firefox and other browsers wouldn't be exactly ecstatic about MS direction with 10...
I do get why they are doing what they are doing..
on the surface ..trying to do seamless integration of all services, ease of use, less confusing for people, etc...
below the surface it ain't so pretty though.
Just as there are different types of linux for different levels of savvy user...
perhaps that is the direction MS should go in ...offer a variety of flavours from beginner to knowledgable ...instead of trying for a universal system like 10 ...that is going to irritate and frustrate everyone equally ...
they did an admirable job on xp tablet edition [once the bugs were worked out] . It and win 7 are still pretty impressive for the onscreen penabled graphic work I do...love it. But personally couldn't stand 8...it's touchscreen interface really felt like it was meant for thick-fingered poking..simplistic interface meant for finger-painting...it wasn't a good interface for my work...it was an honest attempt at integrating touch...but for me..for my graphic work it didn't work well...
