Maybe for hardware. There are pretty good about hardware support. At two companies I worked at we got people sent to us for on-site repair.

Their software support is something else. I haven't had to use IBM tooling in a while, but back when I did, everything they sold was absolutely fucking terrible (DB2, RAD, WebSphere, Clear Case, Tivoli) compared to many open source equivalents.

The only reason people buy this rubbish is because they're in an old company (bank, insurance, etc.) that has relied on it for ages and don't care about the inefficiency or cost.
