I dont have any affinity to either MS or Sun or any company. Look at the industry, how it has responded to quality products. Later VC took its place. Just like that because Sun is providing the best UNIX servers around, people will go for it just like they might go for Cafe from Symantec.
Nothing is indispensable in the fast-changing world .
Windows and even Java may have to make way for a better product. Time will tell. If major new technologies evolve, then they ought to be handed over to independent bodies. Sun should give up Java and MS , the ODBC std. But on the whole , the current trend of some companies grouping together to form a lobby is not a good trend.
