if i want to convert linearly...
72MSa/S @ $199.00... 1GSa/S will be $2763.89
12 MSPS @ $297.99... 1GSa/S will be $24,832.5
dude, where you get your math? do you primarily considering this stuff due to asthetics? or try to impress some chicks?
and this is the real joke... Oscium Site...
"which is why it's the preferred scope for the next generation of inventors."inventors?

inventors dont need iphone to invent! all they need is just a few rusty crappy metals.
last night i stumbled with 3GSa/S chip (chip alone!) that cost 3x the price of a complete Rigol, my point? ADC is the most important/expensive part in the DSO.
if you are considering portability, why dont you try to consider Hantek DSO1060 60Mhz or even the USB version 5GSa/S PicoScope 6402, thats more logical in term of math (price/sample rate)
