The performances of windows 8 and windows 7 are very similar, I see no major performance benefit from upgrading at this moment; same logic applies vice-versa - no major dis-benefit from upgrading. Windows transition perspectives: Pros: -New metro UI - I can see some people liking it, some "fine" with it. (Opinionated) -Rebuilt architecture - Too early to talk about, but it's either going to boom or bust -New features - What can I say, new features... Questionable(s): -Compatibility? - full dos functionality, physical boot control, legacy application that could not even support 7's explorer and had to be loaded outside of explorer; emulation is a solution for many of this but how much is natively supported? -Control? - UAC, and how much tasks can 8 unload while still having functionality? Cons: Metro Look - some people will not take it, others require the desktop for special startup, some simply do no wish to run 3rd party program but will ultimately be forced to do so just to accomplish 7's cosmetic design.(Again opinionated) New Features: Useful for some, bloatware for others. Unless it's something that just couldn't be implemented for 7 due to change of architecture, otherwise everything can be ported, even the newest toys/gimmicks. ----------- Understandable workaround with "start 8" (not free, 5 USD for basic; 50 USD for Professional). Some will say: "but why bother if you already have windows 7". Others don't support 3rd party add-on's. But, if you do use windows 8 and want a start menu, more power to you. It does many things, which makes me question it's security and vulnerabilities; which I believe to be safe thinking on a user/administrative perspective. 1) Does it: not use the metro UI aka negating it or simply just bypass it aka processing it then accessing the desktop quickly. 2) Not free, being charged for something windows 7 already provides. But, if you must move on, your either going to adapt to 8 or buy in start-8. ------------ Assumption: A lot of people will be jumping boats regardless of what happens. Others will wait for favorable/forceful adjustments to jump boats. The rest will be holding out; XP has been famous for a long time, 7 looks like it's going to be a tough one as well.
