again people miss the point. back in the days of 16 bit computing , the PC market was not even a 4th the size it is today, back then it didnt matter that most the market was on 16 bit , because most the market then had about 1 million users that would likely have a 90% upgrade ratio not to mention the market was stil growing and MS could make the diference up with new buyers particularly when pcs would start moving to main stream and 16 bit was never main stream any one that thinks it was , has their heads in rich man's la la land.
fast forward to todays PC market ,
Every thing is main stream now ,
powerusers make up the smallest section of the market at this point as opposed to them being "the market"
most people that make up the market are low end to middle end users that msotly browse the internet or do light work on PC's they see little reason to go out and buy new hardware , and the vast majority of them don't even understand the technological difference between 32 bit and 64 bit . most of them want a pc that works , and that's all they care about they don't care for the latest and greatest and they certainly are concerned about upgrades that may cause them more problems
the pc market now has a whopping 50-100 million consumers now the larger portion of which are the main stream guys /girls mentioned above.
granted the "hardcore" crowd still consist of roughly 1-2 million of those people it is a tiny percentage of the market when you look at the numbers.
now imagine if MS made win 7 64 only the vast majority of that market, does NOT want to uopgrade not for a new OS when thier old Win XP works just fine for them , and it doesn't require new hardware. this would equate to MS having a massive hemorage of money going into an OS that few people would buy. however they release a 32 bit version and advertise the bells and whistles of the OS to every one and at least half the 32 bit users wil decide to get the new OS also if for no other reason than to just check it out since they can get a flavor that doesn't require a new PC purchase. throw in a general economical crisis ,and 32 bit version of the OS makes more sense because even fewer consumers wil be willing to buy all new hardware.
so you can say 32 bit is holdign the industry back or you can say MS is holding it back , but in truth you are jsut an idiot that is talking out your anal cavity and you have no clue. the MARKET drives innovation or lack thereof not the companies Ms is trapped in this as much as us power users are if MS doesn't porvide backward compatibility at this point THEY will loose Millions if not billions of dollars from both loss of sales , as well as loss of investors for being so stupid as to ignore a hefty chunk of thier consummer base.
and lastly i'd like to add that you guys (or gals) that think the market should pander only to you because your a rich ass kid with rich ass parent have your heads stuck up your ass for not realizing that the whoel world is not as rich as you are. sure newer computers are "only 500 dollars" but for most consumers 500 dollars is NOT chump change . so grow the f--- up already and stop expecting the world to evolve around your minority bursting wallets.
