I just returned my POD GO today, after buying it yesterday. I was really not happy with it on many levels, but especially one. Linear signal chain, you can't really run dual amp setups or anything like that. As far as i could tell in my limited use, you can't even choose where to put the amp and cab really. My gen 1 zoom g5 is as, perhaps more powerful than this thing. The zoom is still linear, but at least I can put a couple amps in the chain in series if I want. Modeling to my ears sounds pretty good across most of the platforms, they really have it down. But for like 100 more bucks, you can get an hd500x and have a lot more control over your signal chains and such.
As far as the presets, and sound itself goes, it's fine. The switching isn't as intuitive as the zoom, but it takes up a bit less space, and generally looks better as a unit. the packaging is very nice and colorful, the unit has really cool multi colored lights, and an easy to read display.
But without being able to fool around with your chains, it stifles creativity, even more so than other products in it's class, and I just can't have that. I am sticking with my zoom until I decide if i want to go HD or HX
