All of the devices listed are "really portable". They fit in your pocket. The SSD devices are pretty close to being SD cards with wifi.
If you chose an Android tablet without an SD slot, you could use an SD card, a USB OTG cable and
Stickmount.
As for your question about the Transformer vs. the iPad, I think it's difficult to judge without trying both devices. Obviously, 11.6, 13 and 14" sound better than 10" if you're only concerned with not having to manipulate or resize an A4 (8.27 × 11.69) pdf in order to see all of it. However, the user experience is hard to quantify purely with specs. Apple stores are fairly ubiquitous -- why not try going to one and viewing an A4 pdf on an iPad there?
