Use Raid 0 for OS (with cavets)

You should seperate the data you use vs the programs and OS that you use.

Additionally assuming you can plan ahead build the OS and programs on Raid 0 which will double your read write speeds that allows the system to self distruct if something goes wrong but can easily recover if you have an ongoing backup solution..

instead of the 1200MBit/sec you can have 2400Mbit/sec (remember that this is shared so it drops down by half or more with multiple operations)

OTA HDTV in GVRD (free)

I don't want to pay for TV signals, the why bundles work you typically more economical to however I don't like the idea of being cut off from local news. Fortunately this is where OTA comes in. This is just a pointer to a old page that has kept up with making as well as recieving the 4-6 OTA channels.

  • CBC – CH. 58.1
  • Global – CH. 22.2
  • CTV – CH. 33.1
  • Omni – CH. 42.1
I hope allow my multiple TV's through a signal cable but that would mean having multiple wires throughout the house.
I may have to resort to streaming via DLNA.. won't that be fun. http://alenblog.wordpress.com/2011/04/24/watch-online-tv-ppstream-pplive-etc-on-tv-via-dlna/

Truth about LED backlit

LED is a newer technology primary reasons for introduction is lower power consumption in laptops (CCFL of the past drain the battery very quickly in comparision) and the longer life of the LED itself.

The problem is if you care about color. LED backlight especially in the lower end of the pricepoint have inaccurate color. ACER is known for this, samsung apparenty has a better reputation but it has to do with the design of the LED, it does not generate white light instead it gives off a blueish white which will effect your colors accuracy.

It's actually cheaper to make LED but because of the limited supply it has jaked up the price.

In short LED backlit laptops are good since portability is more important but when it comes to desktop units, color if that is important to you shouldn't be sacrificed and you need to look at the screens for yourself if you can tell.

Also remember backlit can mean edge lit the most common or more expensive backlit where the entire back is being lit. the TV market gave up on this because it was so expensive to produce.

samsung tablet Series

480 (1280 x 800) 10.1 @ dual 1.0
250 (1024 x 600) 7 @ 1.2 - ir
480 (1280 x 800) AMOLED 7.7 @ 1.4 - ir

the 7.7 normally retails for 700 becuase it has LTE,, the 250 version also comes with an IR

all reports that the AMOLED is better than the Ipad 3 in terms of display

USB 3.0 'speed'

all this future proofing is a hard gamble. Things will always be faster or sometimes get sent aside..
SATA-III - 6Gbit/sec
Sata II- 3Gbit/sec has a bandwidth of 600MB/s
Some high end SSD bare drives can write at well over 300MB/s 
Mechanical drives peak at a sustained 140-150MB/s or so.



SSD based raid USB3 connections can be 300MB/s

Clunky and manual way to redo your library

If you move media files around you'll end up with missing entries. I found it's easier to do the following to renew your media files on your local computer:

Stop service
Windows media plyer networksharing services


delete all files *.wmdb
%userprofile%\Local Settings\Application Data\Microsoft\Media Player

restart the wdinows media player
