First, I looked at the three listed A2109 models, and unlike the IBM type-model, I see no link between CPU, memory, or storage. It looks at first glance that Lenovo did the MSU routine. "Web Model" uses the IBM-like Type-Model, while the non "Web-Model" use a part number... Apologies for the horrid formatting...

I am tired of seeing stories on the Internet, claiming that the A2109 lacks this or that, or has a horrid screen, or lacks an SD card... like the Allstate ad, "I saw it on the Internet". However, for those of us used to IBM documentation being incorrect at times, YMMV. If someone opens up a A2109 and finds or does not find something, let us know. Empirical evidence wins out every time (or it should!).
