The majority of web3 developers only just recently entered the space, and are looking for simpler tools. We discovered this from a long series of interviews. The goal is to build cookbook in a web2 dev accessible way, and present all of the stats and audits and information so that they are more able to make dapps.
Openzeppelin provides a very limited number of templates. Great for importing into a smart contract and extending from, but requires a fair bit of work to get there. With cookbook, people can use/deploy completed contracts from other projects for many more usecases than openzeppelin.
I would make an embeddable payment widget for this. Provide as an iframe and include web3 dependencies. that way users can pay directly from their metamask
It's hard to say off the top of my head, but I think having stablecoin options is important, ETH, BTC (harder to do with bitcoin wallets). price should be configurable by the seller, so it's just a simple buy button for the vender. most of the POS crypto stuff I've seen is very overbloated, I think the whole thing could be simplified to an iframe button that opens metamask. This is sort of an idea I've been toying with for some time and built a prototype some time back. that's my 2 cents
I think in most cases, NFTs are clearly collectible art. It's hard to say when these projects branch out and become about more, but I'd still err on the side of not securities.
Really depends what you're after. I personally have stuck with mac for the last 5 years for ease of use and build quality. After working on mining rigs, I really value all-in-one to avoid dealing with configuration issues and the like. If you're looking for that fine tuned granular control though, then mac won't ever satisfy.
