TI Bans all Assembly Programming, Casio Limits Add-ins. Please don't follow suit HP.

Right. That said, both TI and HP have done short duration support, or no support, for some of their models

* HP gave up on the 39gII, but I know it's not their fault;
* TI-68k series: the 89 & 92+ received OS upgrades for only ~1 year after the V200 came out, the V200 received OS upgrades until 1 year after the 89T came out - and the 89T itself received only two OS upgrades, the last one a bit less than two years before the Nspire became available;
* TI-Z80 series: the 82A and 84+-T, of which are minor, recent, crippled derivatives of the decade-old 84+, received no OS upgrades whatsoever. There are probably other examples, but I'm less familiar with that series;
* Nspire series: TI had previously supported the Nspire Clickpad & Touchpad for a while after the CX I came out, until their 32 MB Flash memories were maxed out by the OS upgrade, which occurred after OS 3.9 - but the CX I is not about to hit such a limit. I don't remember about a previous occurrence of TI giving up on OS upgrades for a model immediately after the next model hit the market...
