Hi Stando,regarding $$
- well I'd like to point out that you don't have to spend them for useless crap from M$ which needs lot of RAM just for OS itself. I'm using 'old' MacBook from 2009 ( C2Duo @2.13, 6GB RAM...) - yes, it's dinosaur! It cost me ~$1200 (jo v Praze vyprodej 2010 za 24000,- CZK). It comes with iMovie (basic, but very powerful tool - incl. in every Mac).
However it worked well for all these years & true is I've just switch to new Air ~$1500 (30200,- CZK , 8GB, i5 @ 1.8 z Datartu) because of speed starts to be pain. Sure think I'd buy iMac or MB Pro, however you know how is it in our country with $$.
I used to shoot family/friends (mainly celebrations, daily life) still with SD700.
I am not sure as I'm not using it, but I'd bet that s/n from Win versions of Vegas/Premiere/others will work also on Mac versions.regarding your videos
well, they're ok, every work could be criticized, but are you professional? or you're creating because it's fun?
for me are transitions missing & I think they'd move your movies much further. I like your exposure - is almost 100% (I watched more your videos), only in few parts looks too dark otherwise well balanced - but hey, many ppl will tell: "that's intentional!"
It's not a dogma, just story/opinions from another person....
Good luck! / Tak hodně štěstí!!
