Its been written elsewhere that vsta is likely to be the last windows version due to its almost impossability to maintain. Its grown so big that even the developers cant maintain properly.
vista will have a slow start in life because its not a big upgrade over xp, it doesnt do anything meaningful that cant already be done and it doesnt appeal to any group in particular either. the only peopel using it will be those who have it forced upon them when they buy their new oem machines.
The gamer doesnt like it due to its remove of audio acceleration so will depend on support of OpenAL and dx10 may be a step forward visualy but at a cost of cpu power and dx9 is done through an emulation layer into dx10.
the business wont be able to take it up due to vistas highly complex nature meaning many weeks of testing before even thinking of deploying, not to mention the horrendous cost of the new os and the fact that all current machines will need to be replaced to run it. vista simpy isnt ale to perform on current p2/p3/p4 machines that grace millions of offices currently running 2k/xp and just about perform well enough.
the drm meassures are there to help the greedy and stop the user moving content to there other devices no mater how much was spent for the privilage of beeing able to watch baught content at least once.
ive gone through all ultimate t4est versions and final, and apart from eyecandy there is no real reason to use it. generaly takes more steps to get to what you want and actually loweres productivity due to the imence resource requirment that vista utilises.everything is pretty nippy and instant (by comparison) under xp athough nothing matches amigas os for things happening the instant there called upon.
im unsure why people seem to think vista is free from viruses and such because while its lightly protected now, it just takes a talanted virus writter a little extra work to beat it and those not running any kind of anti-virus well...more fool them.
