You guys color your "market analysis" with personal opinion way too much. Apple isn't going away and neither is Samsung. For the most part, there isn't a ton of overlap in their targeted segments, either. Apple's global share should shrink, since they target the high margin segments at the top end, whereas Samsung (and HTC, Motorola, et al) target a piece of that high end plus just about every other segment down to the dumbphone level. Those companies' shares SHOULD grow as the market shifts toward smartphones even at the lower end.
Don't let your personal opinion of either company or your enthusiasm for their particular brand influence your analysis of the market. Both are profit-seeking entities looking to extract every possible dollar from each other, and more importantly, from you. Blind loyalty, and equally, blind disregard, for any company is a ridiculous notion. All that makes you is an inelastic consumer, which Apple, Samsung, or anyone else, loves.
Buy the best tool for the job and let these companies fight for you. The only other group that has this kind of brand loyalty that I see around here are cigarette smokers, and maybe Saab owners. Is that really the level of uninformed we are as a consumer group?
Disclosure: I'm long AAPL, GOOG, QCOM either directly or through funds. I'd be long Samsung too, if they traded on a US exchange. I also own an SGS2 and many Apple products.
