Compact Digital Camera Under $200

I'm looking for a compact digital camera for daily use with full manual modes.
I found Canon PowerShot A570 IS good solution. 
Basic features:

  • 7.1 MPix Resolution
  • 4 x optical zoom (35-140mm equivalent of 35mm film)
  • Manual mode, Aperture Priority mode, Shutter Priority mode
  • Image Stabilization
  • SD card, 2 AA Bateries
  • dimensions 90x64x43mm 
  • approx. price $180

Digital Camera Resolution - Is Higher Always Better?

Todays compact digital cameras have 6MPix resolution and higher (up to 12MPix). Even some cell phones have 3MPix cameras. So when you buy a digital camera is the resolution the main feature what we should look for? Absolutely NOT!
Let's count what resolution we really need. The printer resolution is enough from 200 to 300DPI (Dots Per Inch) - let's count 300DPI. The most common used format is 4x6'' (10x15cm). So if you plan to shoot (and later print!) mostly on this format the picture size should be 1200x1800 pixels. That is 21600000Pix = 2,16 MPix. So the 3MPix digital camera is just fine even for 4.5x7'' (12x18cm)
Bottom line is that when you look for a digital camera more than the physical resolution focus on modes and functions you really need. Ask about the lenses, focal length, "zoom", etc. Consider the size and ergonomics.

Looking for LCD TV

Requirements:

  • 37" (16:9)
  • S-PVA technology (or S-IPS)
Not sure about resolution yet
  • 1920x1080 px (full HD)
  • 1366 x 768 px
The palyers so far:
  • SAMSUNG LE37M87BD (don't know screen technology yet)
  • SAMSUNG LE37R86BDX
  • SAMSUNG LE37S71 
The SAMSUNG website doesn't indicate the LCD techology of TVs. Regarding to this page I found out that Panel -"Super Clear" means S-PVA. Unfortunately SAMSUNG LE37M87BD doesn't use this technology.
