Samsung

So I was unpacking the so-called Samsung Hero. A phone that costs a mere 3500 bucks (I got it for free btw). I was pleasantly surprised.
The build quality of the phone is superb. The keys are big and have a good feel. Tactile. Easy-to-use. The quality of the plastics used in the phone is phenomenal. It has a nice velvety feel to it. I'm mighty impressed with Samsung. I had expected a cheap, low-quality Korean product but was surprised to find a value-for-money, high quality product from Samsung.
I am, btw, a stout Nokia supporter when it comes to phones for alot of reasons but after using this phone, I'd say I'm pretty open to buying a Samsung phone, in particular one of those slim Ultra edition phones.
Sony-Ericsson is a strict no for me, due to reasons, namely:-
1. It's a Sony
2. I don't like the memory sticks. Proprietary shit.
However, they're walkman phones are pretty good. The quality is great and they have some neat features. However, the lack of a real OS is at times annoying.
Motorola? Awesome looking phones but an equally horrible User Interface. The standard UI used for the RAZR, KRZR, SLVR, etc. look like they've been ripped off a 5 year old colour phone. It's absolutely shocking that a company can get away with something so disgusting.
That's why Nokia is the best. Great build quality. Symbian kicks ass. Feature packed phones. Legendary ease-of-use and user interface. However, they don't do to well in the looks department.
Samsung looks to be almost as good as Nokia and with the kind of money they're pouring into R&D, they'll probably trounce SonyEricsson and Motorola in the near future.
