VFM - Acer
Aesthetics - Sony Vaio
Performance - Acer (if hardcore gaming) else no real difference (normal usage+some gaming)
The solution (for normal usage) -
Visit any big store (Vijay Sales, Croma), put them side by side and the buy the one you feels looks best and performs best in a rapid 10 mins testing
hyeah:
The Solution (for gaming) -
Go for the acer and you won't regret it. Will be able to run most games at med/high setting in native resolution.
The Solution (for DTP usage) -
Go for the vaio, greater resolution allows more text in the screen.
Finally the solution (for mobility) -
Acer has better battery life compared to Vaio (acc. to specs in website). Acer gives 3 hrs while surfing through wi-fi in power save mode and that's acceptable.
