IBM has made it incredibly easy to order PTFs, unless you're the Slowskis.
I love the IBM download process at Fix Central. Once I got all my entitlement stuff straightened out, I've since had no problems ordering PTFs and groups and cumes. My only problem is that I don't happen to have a 5MB Internet connection. In fact, I have a 384KB SDSL connection, and even that doesn't always kick in at much more than about 30K bytes per second. This wouldn't be a problem except that my last PTF order (cume and groups) was 3.6GB in size, as you can see in Figure 1.
