New PPC 970 Laptops
Ok, after doing some sluthing I came across a PPC 970 pdf that IBM has on there site.
http://www3.ibm.com/chips/techlib/te...70_MPF2002.pdf
Noting that on page 14 it shows the specs on the new PPC 970. The 1.8ghz dissipates 48 wats of heat... this is fine for the new line of PMs but far too high for the new TiBooks... Just below, it then stats that a PPC 970 running at 1.2ghz will only dissipate 19 wats and draw 1.1 volts. This is perfect for the new TiBooks, and it would be a healthy speed bump to the whole line.
I for one would like to have a 64-bit PPC in my lap.
Would this be the first 64-bit laptop created?

I think a 970 based 15 inch PowerBook is a given at WWDC.
Also a 970 based desktop
and some kind of bluetooth capable "better than a PDA" device.

I have heard about the uncomfortably warm feeling people notice using the 12 inch TiBook. Hopefully the lower displaced wattage takes care of the problem.
many many people at sun have moved up to powerbook titaniums and the unix OSX provides for it.
even gosling the "father" of java moved to a powerbook.

I took a look at suns website but there is no sign of a laptop (32 or 64 bit)... must have been a complete failure.

The Sun laptop was around in the mid 1990s. We had one at work. It wasn't bad, but clunky slow. They stopped making them shortly afterwards.

There is still laptops with sparcs out there...

Like here.
Love the line, "PARCLE® notebooks from Tadpole® are the most affordable, full featured UNIX notebooks money can buy." What about an iBook?
_440MHz, 500MHz or 650MHz UltraSPARC® processors
gee unless Sun gets their mghz up all their customers are going to switch to Windows. blah blah blah..
September at the latest?

Amen...and here's hopin.
The 7457 uses:
at 1GHz, 15.8W Typical, 22W Max.
at 1.3GHz, 18.7W Typical, 26W Max.
So if we assume the 970's 19W corresponds to what Moto calls the "typical rating", then at 1.2GHz the 970 is in line with a 1.3GHz 7457 G4.
Also note that the current G4 used in Powerbooks is a 7455, so it's typical power consumption is probably going to be higher than that for the 7457. A 1GHz 7455 may consume as much power as a 1.3GHz 7457...
[edit-- from here, it looks like the 7455 uses 15W typical, 22W max.]
Why would apple need such monstrous heatsinks in there line of PMs when the chip only gives off around 20 watts each. I have seen Athlon based PCs running around 65-75 watts with much smaller heatsink and fan setups. Also the PDF Gamblor just linked to stats that the typical watts are after the I/O power and PLL power are taken out.
Smelly alright...
[edit-- I should also note that Apple has traditionally tried to build their machines to be quieter than the typical PC. I'd imagine that's at least partially responsible for the massive heat sinks on current machines, even if they didn't really succeed in reaching their goal.]

Also remember that the towers are duals, and therefore the large heat sinks are needed. Dual 1.4GHz could be giving off around 50+ watts (maybe more, this is just trying to guess based on the 1GHz part). The single 1GHz probably could go without the large heatsink, but problably it is easyer (and cheaper) for Apple to have a "one size fits all" strategy here.
[EDIT] I just reread your post. If it is true that you have seen PCs which dissipate 65-70 watts, with smaller fan/heatsink setups what is Apple doing? Or are the numbers MOT is putting out not exactly correct?
What if they created a new case that has heatsinks around the outside and heatpiped the heatsink to the case, this would cut the noise.
I got the idea from...

The chips that Apple uses in the current Power Macs are low-voltage 7455s (MPC7455B?) that run quite hot. They're a little different than the regular 7455 used in PowerBooks.

While Apple is not going to go into the telecom market, PDA would look like a viable option as Palm isn't seeing it's better days.
It would seem likely that the 15" version would be the first to get the upgrade also, but it would make more sense to do the 17" while your at it.
Introduce the dual PPC970 23" TiBook, as a kicker it doubles as a snowboard.
