Personally I don't see much value in a PC GUI wallet. In order to make in-person transactions possible, in order to reach the many unbanked who have no PCs or have PCs with no Internet, you need a mobile wallet. The main value of a PC GUI wallet is (1) online shoppers stuck in the 1990s, and (2) forcing trolls to be more creative.
There is a lot of value in a PC GUI wallet if we want to attract new users. There are lot of traders/investors out there who want to buy monero for its disruptive ring sig technology but are not willing to keep the coins on an exchange. These investors are not proficient in using command line wallet. and the .NET wallet is not reliable as well. Even transfer from one exchange to another is still not possible. Also we need to make it easier for new exchanges to list MRO. currently only poloniex is the only well known exchange to list it. we need BTER, Mintpal and Cryptsy as well.
Now why do we need new investors and exchanges who cannot even operate a command line wallet? Because we need MROs price to rise. MRO market cap may not fall much from its current value in USD/BTC but with every day passing, value of each MRO gets diluted because of majority of newly minted 24K new coins dumped everyday. This cause coins price to decline steadily.
I have seen a lot of posts in here saying that price of MRO does not matter and we are not after making a quick profit but to develop something new from scratch that will change the world. Similar posts were prevalent in Dogecoin. I am not comparing MRO with Dogecoin by any means but still there are lessons to be learned from failure the of Dogecoin.
A) No matter how involved the community is price of coin will not rise unless there is something done to absorb all the new coins in market.
B) If speculators/investors don't see value of coin rising, they simply will not buy it and without them price of coin will not rise.
Why do we need MRO price to rise? because there is little motivation to donate to bounties if the coins price falls. Lets say I buy 1000 MRO today for 4 BTC. After a week if they are worth only 3 BTC I will either hold them and forget about it or in worse case sell them at loss. But if it worth 5 BTC after a week and 6 BTC after 2 weeks. I have vested interest in coin and i would be happy to contribute 10 MRO to the bounties hoping it will further raise MRO price. Also more coders/devs will want to get involved if MRO price is on rise.
