I will purchase either A55 or the NEX-VG10 for my son. Reason: making movies.
OK he's just 15 but proved that he can. His last home made movie was long enough, lasting more than an hour (script, plot, cinematography, directing, editing etc all by his own). So have to upgrade. We discussed a lot. After reading all specifications he's more prone for the ... yes, A55


VG10 can record with no limits (except for batteries and card capacity), A55 can for up to 29 min without SSS on (or 9min with SSS).
He mentioned: who does a scene for more than a couple of minutes


So I need some advice. Is A55 enough or should I look toward NEX-VG10 ?
You might as well ask questions to be more specific.
Please help.
P.S. as a future movie director, I want him to learn photography a lot, but let this not be a reason for the choice to be made.
