VIA uses Ball Grid Array soldering which requires special equipment to either solder or un-solder.

Thanks all! Maybe HP made another great design decision by making the outer case aluminum instead of plastic - for heat dissipation. A Mini-Note with better CPU change might be bigger vent holes. E.g. when I look at the pictures of the side of the MSI Wind (plastic case) it looks like the fan holes are huge! If the Mini-Note got a more powerful CPU we might expect some big vent holes, too.

This could be an error, but given how hot the 2133 runs, I have a hard time believing there is a ULV 1.6Ghz C7-M in there.

Processor's are offered in a range of speeds, the slower CPUs being closer to the Min TDP and the faster one's being closer to the Max TDP. Isaiah is supposed to have a min TDP of 3.5 watts and a max of 25. We will have to wait and see where a 1.6Ghz Isaiah falls into the TDP scale. According to Via's website, the C7-M 1.6Ghz (like in the 2133) has a TDP of 15W. Only the Ultra Low Voltage models have a 7-8W TDP. Don’t forget there is a Min and Max TDP.

According to wikipedia the 1.6Ghz VIA C7-M ULV chip has a 5W TDP, which is 4 or 5 times less than Isaiah's 20-25W TDP (no official word on that though) So it does seem like Isaiah might not be the best bet for these mini-notebooks.

It's more complicated out-of-order design and has a larger cache, so it would have to be more expensive. But Atom isn't exactly cheap either. Silverthorne Atom 1.6Ghz is $90 and the 1.8Ghz is $160 including the $25 SCH chipset. Diamondville will not be shipping with SCH, but will use Intel's 945 chipset, so I'm not sure what kind of price difference there will be, but I would be hard pressed to believe that Isaiah would be more expensive then this. To put Atom's high price in perspective, for $88 you can get a retail Socket P Mobile Celeron 2.0Ghz from Newegg, so I'm sure you could get a slower ~1.6Ghz-1.8Ghz Celeron in OEM (Qty 1000+) for much cheaper than Atom.

The non-ULV Isaiah part, I think, has a TDP of 20~25W, which would be too much for 2133-like devices. Via hasn't mentioned when a ULV Isaiah would be available, but I am guessing that it will take a while. I think HP will stay with the current C7-M-based design for a while. They COULD go with an Atom-based design, but why? They should sell the current design till they recoup their investment. I don't see any major design change from HP on 2133 until the end of the year. At which time, Via could be ready with a ULV Isaiah part or HP has to go with an Atom-based design. Hong.
