is the pc obsolete?

I keep reading blogs about a tablet mac from Apple.  I hope they don’t make one.  My first computer was an IBM 360/50, and I loved it, but somehow when personal computers came into my life, I didn’t miss mainframes. Mainframes were good at updating massive sequences of numerical data.  Checking accounts, utility bills, stuff like that. In that mindset a personal computer didn’t, well, compute. The amount of data that fit on a floppy disk was trivial. But it got the programming out of the box. And just about anybody would write a simple BASIC program. I still think of PCs as a way to store my text, but I’ve noticed that everybody else seems to use to store music and photos and craft their home videos.  But it feels like PCs don’t have much further to go.  What else can they do?  A tablet PC is just an untethered PC, kind of like, you know, a cellphone. Cellphones can take pictures, handle data, connect to the internet, handle debit transactions, locate you with GSP.  Some of them anyway.  All it seems we’re missing now is decent voice recognition/speech recognition.
