As long as this keeps up the manufacturers have every reason to continue deliberately avoiding standardization and keep controlled stage propitiatory devices, carts, etc etc.
Yep, there is a good side in this - let the markets (eventually?) start narrowing it down to the best of the best. I also fear this makes a big 'stumbling block' for the mainstream masses.
Anyways, yep, I got caught (to a degree) and its why I always recommend first-time buyers do go for something... at least somewhere up there in the middle in terms of power and 'latest'. Ego for example. Just try and stick with that for as long as possible and then again, when you upgrade - really upgrade.
But yeah, its really dangerous having an account at a few good supplier websites nicely hooked up to the paypal account (or credit card) and with just a few clicks - voila - the latest gizmo, tweak, mod, upgrade heheh
