^^ Nokia is good untill the functions phones were on the hit.. but when these touch screen phones came it market, HTC made its name..
Though the strategy HTC took wasnt much good as they first used the Network operators own logo and their own name for the models and now they are stick to that although they are releasing models with their own brand name and models names.
The pioneer of touch screen is actually HTC and windows mobiles are on HTC for long.
Windows Mobile may be on its way out (or so it seems) but for now its here and very grounded in the corporate market. Its got the best, native integration with MS Exchange (incredible market share of that criterea). Iphone does integrate but leaves so much to be desired. BlackBerry does, but you need to spend another few grand for the enterprise software.
There maybe limitations to WinMo, but there are some items that iPhone doesn't do (yet) and Google and other Linux based phones haven't caught up with yet.
Why are people always looking for "what will be", enjoy "what is" while you can!!
