Difference between U46E-RAL7 and U46E-BAL7???

Hi All,

Newbie to Laptop forums - I came across these 2 ASUS laptops and both seem great but obviously a $100 savings is $100 bucks!

So I am Looking at either the U46E-RAL7 ($699 OfficeDepot) or the U46E-BAL7 ($799 @ BestBuy). I left out some specs (webcam / speakers as I don't care about those... )

ASUS U46E-RAL7 Laptop Computer
14" LED-Backlit Screen
2nd Gen Intel Core i7-2640M CPU @ 2.80ghz
8GB DDR3 SDRAM
750GB 5.4K HD
Win7 Home Premium 64bit
802.11b/g/n WiFi 10/100/1000 Ethernet
DVD+/-RW DVD-RAM
1 USB 3.0; 2 USB 2.0; 1 Ethernet; 1 HDMI; 1 VGA 15-pin D-sub

ASUS U46E-BAL7 Laptop Computer
2nd Gen i7 CPU @2.8GHz
14" Display Widescreen LED-backlit
Cache Memory 4MB on die Level 3
8GB DDR3 SDRAM
750GB HD
Double-layer DVD±RW/CD-RW
Digital media card reader
Graphics UMA
Networking Built-in 10/100/1000 Mbps Fast Ethernet
Wireless Networking Wireless-B+G+N
USB Ports 1 USB 3.0; 2 USB 2.0
HDMI Output Yes
OS Windows 7 Home Premium x64
Wireless Capability 4G WiMAX

Initially the specs look EXACTLY the same but in the end the only difference I can see in the specs is that the RAL7 only has 802.11b/g/n WiFi while the BAL7 has 4G WiMAX... I think for $100.. I DO NOT NEED WiMAX ... any thoughts

Thanks in Advance
