Screen technologies have advanced to the point where tablets are outstanding devices for most purposes.

The iPad is a clear winner for watching movies or browsing the web.

But a single-use machine still wins out when you want to concentrate.

Kindle vs. iPad

The flagship Kindle Oasis I own offers tiny but significant improvements over previous models.

The Kindle has the advantage because its tasked with doing only one job.

Its pretty much only suitable for reading books from Amazons vast collection.

Despite, or perhaps because of its limitations, the Kindle functions brilliantly at its single task.

The screens 300 PPI means that text shows up clearly.

The adjustable backlight is nearly enough reason to upgrade your Kindle by itself.

The screen was primitive then, and its still stuck in an era of grayscale.

The Kindle is now waterproof, but I dont know anyone who reads in the bathtub.

The first iPad was sluggish, and even watching movies was at times a frustrating experience.

As an e-reader, however, the iPad falls short.

From a sheer value proposition, the Kindle seems ludicrously overpriced.

A 32-gigabyte Oasis without ads costs $299.99.

The Kindle was easily worth the cost.

Of course, when its time to get work done, the iPad easily wins out.

I just hope that Amazon never discontinues its line of dedicated grayscale readers.
