The poll is biased laa. You're opening this thread in android thread with majority of HTC owner. Nonetheless, here is my take on some of the brand.

Nokia: Been using these since the beginning of time. Legendary, superior and spoilt for choice. But PDA is not their front market although they are planning on some in the future for android.

Samsung: never tried any model, but this company is well-known for its latest technology. Thanks to Samsung, HC and many other brand get to enjoy AMOLED technology.

Motorola: Waay behind the pecking order. Left out of the race after stale market since RAZR period. Now, they are trying to enter the market with milestone and perhaps more to come. I'm gonna make a wait-n-see stance on this one.

HTC: PDA is their key product. Surprising for a Taiwan based company to be able to conquer android market. Expect to see HTC holding on to main pole for years to come. True innovation, open source and unique stlye (google-esque). Just the kind of thing that attracts yuppies.

LG: eye-catching and pretty. Nuff said...

Don't forget FM radio too.
