Intel "Although we didn't consider it as such here today, Yonah will be quite impressive on notebooks. The thought of having such a cool running dual core processor in a notebook is honestly amazing, and the performance difference (especially for multitaskers) over what we have today will be significant. The other thing to keep in mind is that when you go from a single core to a dual core Pentium M notebook, you won't be giving up anything at all. On the desktop side, you normally give up clock speed for dual core support, but Yonah will be running at very similar frequencies to what Dothan is running at today. In other words, you won't be giving up single threaded performance in favor of multi-threaded performance - you'll get the whole package."

I wonder if anyone's tried to put 4 4gb or 8gb flash cards in a laptop in place of the HD? That would have to save you a ton of power and make things blindingly fast as well. For business users that would probably be enough storage if you don't need tons of software installed. Obvously this would be somewhat expensive ;)

Two points to consider. Flash memory is only useful for a limited number of writes. Sure it may be a million times, but hook a flash memory card up to a swap partition for a web browser cache and it's gone in a few months.

second Apple is working on integrating Flash into the mother boards.

My thought on the subject is like this. Put the core OS on a flash disk and use the HD for applications, swap(remember OSX is unix files mount points can be anywhere). The OS will boot up literally tens of seconds faster, Applications won't load much faster but greater storage can be had for the user. (ie OSX takes 2-3 gigs for install) a 4 gig flash card(like the iPod Nano's hint). Power consumption goes down as the hard drive isn't accessed as often.

Increased battery life, faster startup times, increased HD space for the end user, all in one shot. Of course if you could figure a way to hook that flash card into an L3 cache spot on the chip itself that would be even cooler, well faster, and more efficient. though how I don't know.

"Put the core OS on a flash disk and use the HD for applications".

Applications can also be stored on a flash disk with no penalty. Applications (the executable part) are changed not more than a dozen or so times throughout the life of a machine - so they are hardly likely to exhaust the re-write capability of flash disks.

Only things like swap, cache, configurable settings, logs and application data (the actual documents and files that users of the machine produce or download during the life of a machine) need to be stored on a HD.

These guys have been making SSD's (Solid State Disks) for some time now. The link here is for their 2.5" drive you could throw in a notebook. Not so sure on the price, though I would imagine it's fairly hefty (I tried to call them to find out but they had already closed for the day). The primary bennefit of Solid State Disks in industrial applications tends to be durrability. You throw the thing agains a wall and it just keeps on going like nothing happened. I'm not so sure it would be all THAT much faster though. These guys report sustained reads and writes of ~ 28MB/s and bursts up to 66MB/s. Not all that much more impressive that high end HD's nowadays
