Bus service is abysmal;  it's unpredictable at best, and when a bus does finally show up, it's invariably packed.  Using a laptop on a crowded bus can be difficult ... which is ironic in that many of the Seattle Metro fleet now broadcast a wifi signal.

I've started wishing I had a tablet PC.  You need a certain amount of room to open a laptop, see the screen, and operate the keyboard and "mouse."  Often, the best recourse a person has is to open the machine 180 degrees, so the screen runs [as close as possible to] parallel to the keyboard.  You might feel more like you're reading an ancient book - half of the Commandments on their original stone, for example - but there are times when this is better than the alternative.  This doubles the length of the computer, and flattens it, so typing becomes exceptionally difficult.  Operating the mouse isn't terrible, however, especially when the sensitivity is low.

With the passing of my dearly beloved dog, Gino, I've been focusing more on work as a distraction, and doing substantial SQL Server work.  With the 2005 and 2008 versions comes Microsoft SQL Server Management Studio:  the new client tool to replace Enterprise Manager and Query Analyzer in previous versions.  A lot of basic "stubbing" can be done with the mouse - creating a select query that enumerates the column names, for example.  Computer-generated code usually needs some human "improvement," but letting the computer generate most of the code allows closer to hands-free operating of the keyboard.  And when you're working under a tight deadline, being able to work during a 20 minute commute can make a lot of difference.
