I started doing research on the mydevice before all the research apps were taken away from the PDA. When it comes to doing stand alone research, the PDA was much faster than what the mydevice is right now; load the app, scan the item, change the count, wait for prompt vs load my work, switch task to research, scan item, click on update counts, change count, wait for green checkmark. I do like the task list much better because I no longer have to find a pog header to scan when an item has multiple locations.
That being said the mydevice works much faster for research than it did initially because it used to be about 10 seconds for that green checkmark (or red exclamation mark) to appear. It was a nightmare going from PDA to mydevice initially. For me it's about 1-2 seconds for it to clear and I rarely get red exclamation marks.
That being said it's an incredible nuisance that the mydevice will jump around the tasklist if something that has multiple locations is scanned. It should stay on the same aisle until it is manually changed or cleared, not because an item not on that aisle has been scanned.
