yah 2wpg"ish" is probably max'ish' for low tech....and more than you'll need...heck, both my 29g & 55g have only effectively 1.2wpg (see sig link), and another 1.2wpg from Actinic which most folks don't count as "real" plant light...you can see I grow most plants just fine in there...I just don't pick out plants I know have high light demands (well, try not too, being stubborn trying to grow one plant in there that prolly isn't enough light for...).
low tech=slow growth. a 'little' limited on low-tech plant selection. No real daily maintenance. Minor weekly maintenance. Less cost for Co2 equipment & brighter lights.
high tech=faster growth (exciting, but also you have to weed it out). more plant options. daily ferts. weekly water changes. DIY or pressurized Co2 (so consider co2 delivery, drop checkers, all the fun toys).
Kind of up to you....both employ same principals of the hobby (obviously). take a look thru the "photo album" area or nano tanks sub-forum (I don't think 10g is really "nano" but ..sorta...) and see what other folks have done w/ 10g's and either high-tech or low-tech and see what you want to shoot for...both of them will provide challenges, but any good hobby will right? If its not challenging or dynamic you'd get bored of it pretty quick...find a tank or three that "inspire" you....
