so basically you rate the OS on GUI alone...... alot of the stuff under the hood for win2k was passed down to winXP and win7
do some serious work and you'll realize 7 is heads and shoulders above xp, the damn network stack in itself is far superior and worth the upgrade alone, XP although superior to 98 still suffers from resource leaks and kernel bloat and still requires a reboot once a while if your doing some serious work in it (though not as much as 98), driver implementation on 7 is also more stable, win 7 is more able to restart a driver where in past XP would just BSoD
but you really need to get some hands on with win8 to fully appreciate it, most the stuff MS has been harping on is just for the general public to build interest, but for me the real stuff behinds the scene is much more interesting, the kernel improvement feels much better, more zippier, it enters and exit hibernation/sleep far better and using less resources while doing so, you can actually use the machine within 5 secs of coming out of hibernate (5 sec after the desktop becomes available), it would take up to a minute for my machine to become fully responsive on win7
now im no zealot and say it's the best thing since slide bread, i would need to spend alot more hands on time to say for sure, im not sold on Metro Tiles and im still unsure about the new suspend status for applications (some applications now suspend rather than close out, in fact they lack the close function altogether, IE is the biggest offender), but moving between metro and desktop is as easy as a slide or click of the mouse, it's not a use metro or traditional scenario, they both coexist happy along side each other
