I agree phoenix
The 80cm and 110cm lengths are rarely used amoungst Adults, most children will use the shorter 30cm length's of tubing so not sure why they were using the longer lengths unless you are right and they were looking to create a problems..
I use the 60cm length tubing, and find this to really be too long for me, and I am of adverage female hieght.. If I extended the tubing to full lentgh it would be above my head or down below my knees.. My pump spends most of the time either in my pocket or clipped to my waistband and tubing wrapped around it!!
I have seen the Omipod, and yes there are many who like the fact it is tubless and the whole lot attaches to the body, so no tubes to catch or block etc... But as with everything there is always a downside, for the Omipod this is that when wearing it, it creates a lump under your clothing, not good if you into wearing tight fitting clothing...
But yes as a choice for the user then it has valid points to consider it's all down to persnal preferance, and what the indvividual wants..
