If you want to learn the piano, the best would probably be to have a real piano (smallish or grand). But I see no reason either why such an electric apparatus wouldn't cut it for a while. Ultimately, it's about what you learn and as it has been said you will get more in the future if you really want.

I remember I started learning piano on this old primitive keyboard (which I still have by the way). Doesn't go that low and not that high either. But man.... the joy I had with this machine

From what I see it seems you must ask the following question: are you going to be about serious piano-playing OR it is only synthesizers and for what exact purpose? Do you want to record? If you're going to be making music using computers (and MIDI) superior piano playing skills aren't always needed.

For now I'd just say "Get that machine you have in mind and start learning!"
