While I understand the times must move on I personally would not consider buying a keyboard without standard MIDI connections. I use too much older gear Roland JX8P, Roland JV80, Waldorf Pulse, Yamaha TX802 and Yamaha SY77 that I like to be able to trigger from a master keyboard. Sure I don't often use some of these synths often in a live situation away from a computer .... but I don't want the decision of which I can still use without a computer taken away from me.
I'll happily pay the extra $25 bucks it costs the manufacturer ( and probably not even that ) to include these on their keyboards. I'm all for including new MIDI connections in addition to the old ... but I still want gear to be compatible with all the MIDI gear that has come before.
