Depends on what you are using it for. If you want to play games
and use windows stuff then dont get a mac. Even running parallel or
bootcamp on mac won't give you as good a performance as a regular
laptop.
Otherwise, if using for surfing net, using word, normal usage, i
strongly recommend Mac. Ever since switching to a mac, it has
changed the way I use computer. OS X is very intuitive in usage (if
you have used it you'd know). The expose function in OS X is
something I cannot do without now. Very very very useful for
multitasking. OS X also boots and shut down very quickly if that
matters.
There are a sizeable number of apps for all purposes for the mac
and are generally well designed with good UI. Not sure what type of
apps are you specifically talking about but most of these mac apps
are available on the net for web downloads/purchase and are
affordable. Mac does hang at times, but is not half as bad as when
a pc hangs.
i am using both mac and windows but what u say many not be
necessarily true. Whn OSX hangs u just do a reset using some
buttons but i can say Kernel panics are a headache compared to
windows blue screens
