[UPDATE: I have posted my rather extensive review of the iPad. It will be updated frequently!]
[UPDATE x2: I have posted a guide to tethering your iPad to your iPhone.]
I just returned from a shopping trip with stops at Best Buy, Micro Center and the Apple Store (specifically, the smaller of two Apple Stores in the St. Louis Metro Area). A tip for those looking to buy an iPad: DON'T go to the Apple Store. Not only are many Apple Stores running out, but Best Buy also has a nice $30 for $25 iTunes gift card deal.
If you're going to buy at least $30 worth of apps for your iPad, the Gift Card deal is pretty good. Plus, there are no lines at Best Buy. Best Buy doesn't have any accessories, but neither does Apple right now (they're all out of stock).
More to come on the iPad... along with my first blog post from the thing :-)
