Mac...

Both because I want to have a choice...

I think flash will slow things down, but not certain. I just got my iPad for Xmas coming from an android, and I'm really impressed w the speed so far. However it comes w gripes .... It's my first apple product, I'm really a pc ;-)

html 5 is where its at now, but you can use browsers such as atomic web also

I am a PC user. Having received an iPad as a gift, I am enjoying using it and do find it useful in my work. However, I feel restricted by its proprietary nature such as very few music player options that can handle a wide spectrum of formats and no Flash support. I prefer being able use all formats and not be constrained on what I can access. Having said all this, I am interested in seeing where iPad is going and learning new ways to make this device into a useful business tool and entertainment platform.

Hoping to ween the wife from the PC and move to all Apple products.

but without windows you wont be able to get sunlight! lol

I use only Mac! but sometimes I am forced to use Windows which irritates me much!

Voted for Mac, as it's my primary for personal use, but I do use Windows at work.

I voted for Mac, but my employer makes me have to use windows, so I do use both. I have to state it is against my will however. If I had my way I'd use nothing but Mac.
