I just buy new Sony PEG-S320 a couple week ago.

If you want me to score for this PDA, I will score 10 for monochrome PDA !!!

It look slim and good look PDA in the market. It use 33 MHz CPU, with 4 MB Flash rom and also 8 MB Ram with 160*160 resolution. Using OS4.0 make it easy to manage Memory Stick (MS) to back up and run program direct from MS. Moreover, the price is cheaper than competitor such as palm (m500 = $399.99 list price ) and handspring ( Edge $299.99 ), $199.99 !!

However, this PDA doesn't come with credle like palm and handspring ( $50.- extra for that ). It come with USB sync cable and also multivoltage power adapter ( I am not sure about thid because sony mention both 110 V only and also multi voltage on their adapter ). MS is not included in the package but you can get it around the web with the price below $34.99 ( @ circuit city ) for 16 MB which I think it is enough.

The display is look sharp and the backlight is very bright compare with my old visor deluxe and also my sister's palm IIIxe.

It will be pain in the neck for palm and handspring if they don't notice. Like the Clie PEG-N610C that make m505 like a fool !!!

Disadvantage for Sony is accessory, it is not easy to find the case for them. I spend about 4-5 days to find case. Another thing is the media, memory stick is like "sony only" used. However, thing can be change if they keep doing the product to support them.

Again, if you ask me, with is the best monochrome in the market right now, Sony Clie PEG-S320 is the one !!

Advantage :
Faster CPU
New OS 4.0
Very bright backlight
Good display
Cheaper price

Disadvantage:
Memory Stick media
Hard to find accessory
Not coming with credle

where did you find a case that fits right, and now, the PEG-S320 has dropped to $169.99!!
i've looked all over for a good looking case, not one thats three sizes too big, a good looking case is needed

As I mention my cons. Sony accessory is really hard to find. I used to have the flip case from sony (check at sonystyle.com the flip one, PXX-10) But the problem is Velcro tape that you have to sacrifire your S320 to put it on.

After trying to bid on e-bay and think that it is not worth $50-$60 for PDA with $170.- tag price. I just found one on ebay. But you can buy it follow the link,

www.pdapals.com. The price is reasonable for S320 (17.99 with US shipping include) However, It look like it design for N serie Clie. I order one, and I will try it on and post a result for that.

Good luck on your new PDA !!!
