This is for Dick’s benefit.
Yamaha are the world leaders in keyboards aimed at the beginner market. There is something like 12 different models to choose from, all similar and all with an extensive range if features.
Casio are the next most populous manufacturer in the beginner segment.
Other manufacturers like Korg and Roland only have token models to choose from and as far as Korg is concerned the EK50 is an excellent keyboard but considerably more expensive for a beginner but this is not really aimed at the beginner market.
With Yamaha flooding the beginner market they get owners indoctrinated into the wonderful world of Yamaha and owners frequently seem to fail to look outside the brand as they upgrade their keyboards.
I have seen it myself in Music Stores where people have bought a Yamaha when there is another much superior model which is a similar priced keyboard by a different manufacturer readily available.
The Yamaha E series are the first steps, but pretty soon they can be outgrown and going from an E3 series to a E4 series keyboard, which the EW410 essentially is, will not necessarily offer a route for effective advancement of ones keyboard skills.
The next rung up the ladder is the Yamaha S or SX series which are limited to 61 keys but the principle advantage is an increase in the quality of the onboard sounds (especially with the much newer SX models) and the features which you indicate are not that important.
If features are not important then can I suggest that you consider a digital piano a Yamaha NP12 or P125, then you can have the full gamut of 88 keys, the ability to split the keyboard to have different instrument voices each side of the split.
The concern that I have is that you buy what is the most appropriate keyboard for you and not a keyboard that is a knee jerk reaction to a feature you do not like in your E360.
If you can explain some more about what and how you want to play, the direction you want to head with your skills etc then we can offer more constructive advice.
