Has a Built-In Speaker(s)
The Optoma S311 has a built-in speaker(s), as do most of the other data projectors that have been around for more than two years.
There are a number of alternative multimedia projectors with a built-in speaker(s) currently available which you might want to consider including because of it's better review score, the Epson PowerLite 98 ($560.00), or the Benq SX914 ($1,699.00).

This projector has a 100 - 240V AC input voltage, which is the most frequently found AC input voltage on projectors of a comparable type and age to it.
5 Reasons Against
Does Not Support Full HD
The Optoma S311 does not support full HD. Most of the other data projectors that have been on the market for more than two years also do not support full HD.
Alternative data projectors which also support full HD that you might also want to consider include the Benq W7000+, or the Optoma HD30 which is also higher rated.
Does Not Support Wi-Fi
The Optoma S311 does not support wi-Fi, although it is worth keeping in mind that most of the other comparable spec multimedia projectors that came out around the same time as the S311 also do not support wi-Fi.
There are a number of alternative projectors which also support wi-Fi which you might want to consider including the Benq GP20 which also has a higher rating.
Only SVGA (800x600) Projector Native Resolution
The Optoma S311 has a maximum resolution of SVGA (800x600). That's 77% less resolution than the most frequently found projector native resolution of 1080p (1920x1080).
A SVGA (800x600) projector native resolution is in fact the worst resolution amongst all multimedia projectors of a similar age and type to the S311.
Amongst similar types of multimedia projector the best resolution is 1080p (1920x1080).
Very Small Bulb Power
At only 190 Watts, the Optoma S311 has a quite small bulb power compared to most of the other data projectors of a similar type and age to the S311. The bulb powers of data projectors that were released more than two years ago range from 140W to 580W, and the average bulb power is 250W.
+2 More reasons against
Very Low RMS Rated Power
With an RMS rated power of only 2 Watts, the Optoma S311 has one of the lower RMS rated powers amongst data projectors of this age. The average RMS rated power of data projectors that were released more than two years ago is 8.6W.
3 Other reasons to consider the Optoma S311
Released Over Two Years Ago
It was over two years ago when Optoma released the S311.
Average Projector Brightness
At 3,200 ANSI lumens, the Optoma S311 has a pretty standard projector brightness compared to most of the other data projectors that have been available for more than two years.
If this multimedia projector projector brightness is not bright enough for you then you might also want to consider the Optoma X351 ($599.00) (3,600 ANSI lumens) which is also higher rated.
Average Noise Level
At 28 decibels, the Optoma S311 has a pretty average noise level compared to most of the other projectors that were launched more than two years ago.
If you don't mind having a louder noise level then you might want to consider the Optoma H181X ($533.95) (28dB), or the Viewsonic Pro9000 (28dB).
