It might reduce the number of people switching from PC to Mac, but it's a lot tougher to get someone to switch from Mac to PC than from PC to Mac.
+1. It may reduce switchers to Mac, but probably not increase Mac to PC switchers.
Except that a current OSX user can just buy Windows 7 and use it on their Apple hardware & this change won't show up as anything but a sale to Microsoft (i.e. nothing for HP, Dell etc). Don't need to go out and buy new equipment, just use that "always perfect" Apple setup you currently have.
What will be interesting about the Snow Leopard update is what happens to the pre Intel Mac users. When it comes time to upgrade/replace, will they just stick with a Mac or will they take a look at a Windows PC as they could be one, two or more OSX versions behind the Intel based OSX version. The further behind you are the more changes there are the more open you can be to something different.
The other thing that is hard to measure, where the retail sales of Windows 7 are going. You have the upgraders from non upgradable Windows versions (full version), upgraders (upgrade), OEM copies (new systems), Mac users (upgrade for VPC), Mac users (full new to VPC), Corporate licenses (both)etc.
For OSX, the channel is much smaller & easier to figure out, any retail boxed copy sold = upgrade, all other copies are OEM (new systems). The $29/49 price tag though really should encourage all Intel Mac users to upgrade and quiten the complainers about pricing.
Personally I don't expect Windows 7 to have a major effect initially, things might hold steady, but if the user base accepts it, the Corporate world finally decides to ugrdade from XP and the mainstream media generally respond well to it (as opposed to straight out lampooning it) then Apple might struggle to win over as many converts and may lose some, could just balance out.
This being said, should the corporate world not accept Windows 7 I think Apple has potential to improve dramatically in that area. With so many corporate machines still running XP (my company is one) and many having waited so long to upgrade their systems, there is a good chance that when they do finally do the upgrade they could move over to the Apple world.
Ok, so there are plenty of corporations that won't switch but even if Apple made inroads of 5-10% of the possible market they will do extremely well in hardware sales. Regardless, there is plenty of old equipment out there that really needs to be replaced.
Actually, no, he's totally right. 32-bit computing is limited to a maximum of 4 GB of memory.
Leopard is 64-bit and thus can address more than 4 GB of memory. Windows is sold in 32-bit and 64-bit editions, so naturally the 32-bit version is limited to 4 GB.
And in reality Windows 32bit versions are limited to around 3.2GB of usuable RAM assuming you have 4GB installed. Hence why alot of systems with a 32bit Windows OS go out the door these days with 3GB RAM max. The 64bit versions generally go with 4GB.
