Computing The Odds

I shouldn't pick it up
I dare not set it down
Computer problems causing me
To grumble, rant and frown

Cause sometimes all is well
With its many little parts
Then suddenly out of the blue
It chimes and then restarts

And I'd like a new one now
But I think that I'll make do
I know the brand new models come
In just a month or two

Until that time I'll try
To nurse this thing along
You'll get updates if I am right
And nothing if I'm wrong
