I find some of this behavior typical of Microsoft.
1. Create an interesting, but buggy device that doesn't sell according to expectations.
2. Create a version 2 of the device (Still buggy). Sells better, but still not up to expectations..
3. Software updates for version 2 make it a lot better.
4. Interest generates now that it is getting good and people actually start to look forward to a gen 3 (Even beyond original buyers).
5. KILL the product line, or seriously hold it back with major changes until interest wanes.
By the time some kind of major successor is released by them the best features will be changed or lost and the original group that had interest will get tired or irritated. and move on to another device.
Microsoft has made some interesting good products in the past that it has ultimately just tomb-stoned.
