1) No matter how linux try to as user-friendly as possible,
there still command-line and certain stuff you still have to
remember, there's no escape for it. For normal PC user, why would
they want to take their time to remember since they can use
microsoft windows which they are used to and have been using it for
all this time. As you have know, when humans are comfortable with
certain things, they wouldn't want to change it unless there is
really a reason to.
2) Yup there is a workaround for window software and games for
example using winetools, however it is not 100% workable.
3) Yup not only on servers, in smartphones, some entertainment
hardwares too and some other non-complicated devices.
4) Yup, even if microsoft cease support for Win XP, normal user can
still continue to use it, however if loopholes were to be found
then it will be god bless them. Yea you can say hackers will target
vista by then, but do you think companies will take the risk?
Definitely not. Besides, as time goes people will surely change
their computers, whether is it computer breakdown or those hardcore
gamers, and this is when Win vista will comes with it. Don't forget
computer you buy now will become outdated in a few years, maybe 3
years.
5) Yup if PC is from manufacturers definitely it will comes with
vista. However like I said earlier if Win XP ceased support,
microsoft will not release Win XP anymore, do you think those
custom PC will still be able to get XP? I predict after the next
few months to about a year from now, you will not see Win XP in the
SG market anymore (Not sure about the net though). Besides, if
people gotten themselves a new PC, there will be no reason for them
to get outdated software anymore isn't it?
6) Finally, we will not escape from microsoft cluthes unless
someone invent a more user-friendly (Hardware support, software
support - Linux?), easy to use (no complicated setup - Linux?) and
better interface (click and click - Linux?). Indeed Linux have
better security for now (not much hackers and virus attack Linux
for now but in future?).
7) Yup, Linux do have a XP look-alike desktop, however it is still
kinda complicated for normal user, not as straightforward as
microsoft desktop.
