iPad:

Acer Netbook:
-no touchscreen
-30-60 seconds book-up, heat, noise
They're not in the same category. No one is stopping you from getting both.
But the iPad should be great for casual web surfing while sitting on a couch with its touchscreen interface. Using a netbook on your lap isn't as comfortable IMO.
Please find a netbook with a touchscreen for under $500. They're not as cheap as the regular netbooks.
1. for casual browsing, i use my iphone 3gs(which somehow apparently costs apple more to make cause it is 599... gg on that one apple)
2. Looking at the thing, i bet it's just as uncomfortable as a netbook. You pretty much have to have one hand holding, and another moving around all the time. Unless you prop your feet up like a girl. It gets old, i've done it with a tablet.
