Dilemma with canon cameras

My Nikon Coolpix 4200 is going to die on me soon. Has been surfing and researhing for cameras... wanted to get a high-end compact camera. Finally zoom down two options: Canon SD 800 IS and Canon A640

Differences in two canon cameras

Canon SD 800 IS Megapixels 7.4 ISO up to 1600 Aperature - 2.8 - 5.8 focal length - 35mm (28-105) Shooting Speed - 1.7 fps Shutter speed 15 - 1/1600 screen flip: no Battery: 1 rechargeable lithium New feature: With IS Image Stabilizer (reduced shakyness)

Canon A640 Megapixels 10 ISO up to 800 Aperature 2.8 - 4.1 focal length - 35mm (35-140) Shooting Speed - 1.5 fps Shutter speed 15 - 1/2500 screen flip: yes Battery: 4 rechargeable alkaline

By looking at the specs, apparently i should get SD800 IS because the specs are better. However, A640 has the flip screen, that is the reason why i want to change my camera in the first place! Why is it so difficult to install a flip screen in newer cameras? That's their unique selling point! It's so silly paying something more and getting something less.

Should i brainwash myself that without flip is better than with flip OR lower specs are better than higher specs???

"With flip.. without flip.. with flip.. without flip.. "

Okay decided -> With flip :)
