Great post from StormDriver comparing the first mobile computing device, the Osborne I to the iPad 2 (HT: Hacker News 20). Read the whole article, but here’s a set of summary charts. The iPad 2 is a little cheaper and a little more powerful. Thirty years of progress.
BTW, the price is corrected for inflation in some way. The nominal price of the Osborne 1 was $1795.
