HELLO! I am a newbie to the world of macs (i bought this macbook 2 weeks ago) and my dad wants a bite of the apple.. literally. he bought a 15" 700 mhz imac g4 (one like a lamp). it came with 756mb ram (or sommat like that) and os x 10.1.2 ... the problem is, its not quite powerful enough - we cant even install a decent version of flash. What can i do to pimp it up a bit? (at minimal cost ) I know that at present Tiger is the best i can go on OS front - who knows where i can buy it? and failing that, how can i get snow leopard on it? Thanks! Also, i'm in the UK, so if you could please bear that in mind Thanks!
