Apple announced the iPad today, and I can't stop salivating.
But which one to get? The 16 GB model, or the 32 GB or the 64 GB?
And regarding connectivity, the model with Wi-Fi only or the one with both Wi-Fi and 3G?
My take: Assuming you have (or plan to have) a large library of videos, photos or music, go as large as you can afford. You'll fill it up. But if you don't have a lot of space-hogging media, 16 GB should suffice.
And regarding 3G or not, I'd lean toward getting the 3G capability, unless your budget is tight. You aren't on a contract, meaning that you can cancel (and presumably restart) month-by-month service anytime. So if you were traveling or somewhere where you'd otherwise have to spend a chunk of change to activate Wi-Fi for a 24-hour period, buy a month's worth of 3G coverage instead.
