I figured I'd post that stuff above just in case.

So I've narrowed it down between the Hp HDX16t and the Sony Vaio VGN-FW390

The current specs I've got on both of these are as follows:

Sony Vaio:

Intel® Core™ 2 Duo Processor P8700 (2.53GHz)

Microsoft® Windows Vista® Home Premium 64-bit
Titanium Gray
4GB DDR2-SDRAM (DDR2-800, 2GBx2)
500GB SATA Hard Disk Drive [5400 rpm]
Blu-ray Disc™Read Only Drive
ATI Mobility Radeon™ HD 3650 with 512MB vRAM
LCD 16.4" (XBRITE-FullHD™)
Large Capacity Battery



Hp HDX16t
Genuine Windows Vista Home Premium with Service Pack 1 (64-bit)
• Intel(R) Core(TM)2 Duo Processor P8700 (2.53GHz)
• FREE Upgrade to 4GB DDR2 System Memory (2 Dimm) from 3GB DDR2 System Memory (2 Dimm)
• 500GB 5400RPM SATA Hard Drive with HP ProtectSmart Hard Drive Protection

• 16.0" diagonal High Definition HP Ultra BrightView Infinity Display (1366x768)
• FREE Upgrade to Blu-Ray ROM with SuperMulti DVD+/-R/RW Double Layer

My main concerns at the moment are battery life. I've chosen the highest capacity battery on each and both sites HP and Sony boast high battery life, but I've learned not to trust stock ratings and am really concerned on the battery life of each.

Does anyone have any input as to the differences in battery life between these two? Like some actual numbers under use ie playing a Blu-Ray, web surfing, etc.

Any other input to help me decide between these two machines would also be nice.

Thanks
