No one criticizes Samsung and they are pretty much a mobile-OS whore: SHP, Bada, WP7, Symbian (albeit a year or so ago), Android, Limo, etc.
N.B. Regarding SHP: I can't remember the name properly but this was the old/existing Samsung feature phone platform, it probably has got rolled into Bada, although Bada has two configurations (with and w/o the Linux kernel).
Except me, maybe. I don't know anyone who's been satisfied with a Samsung device. I certainly wasn't with mine.
Samsung's business is in selling phones, not developing a software platform and therein lies the problem. They make their bread and butter on planned obsolescence and in the process screw over their customers.
Maybe they just want to focus on selling profitable phones... Not every business model should depend on a single software platform.
Once the operators (typically) have added their crap on top it leaves you little margin to extract extra cash until you get someone to buy another device.
Nokia is renowned for their hardware build quality - well in advance of LG, Moto, or Samsung. I think the market has spoken that they want the full experience - solid software, beautiful hardware, and impeccable integration of the two. Samsung IMHO has fumbled that ball up until now, producing cheap-y hardware coupled with lazy software integration. There's a lot of room for someone who knows what they're doing with Android to come and eat their lunch.
