For years now, along with my wife, my most faithful traveling companion has been a laptop. For a while it was a heavy dude–a Lenovo Thinkpad with a version of Windows; the hardware was bulky, the software balky. I nested it in a leather bag I slung over my shoulder and lugged it through terminals, into and out of hotels. Then came a MacBook, a lighter load, a faster operating system. Sleek, fast. But still: heavy.
Next generation writing tools are more minimal (or less maximal): my IPhone and an iClever portable keyboard, a tri-folding device only slightly larger than an iPhone. In a bar or coffee shop I can prop my phone up on a bag of sugar. I can draft in GoogleDocs on an actual keyboard, post text to my blog, and upload pictures. One device to ctharge at nigh. No limits, as far as I can tell right now.
