Edit: Tried Lion on Macbook Air = Lots of Lag

Happy I didn't sell my Air for this refresh

Must be the decreased performance of the Intel graphics causing it.

 

are you 10000%% sure they had SB processor? maybe u saw a core 2 duo

 

I'd be VERY surprised if this were true.

 

Yup, must be.

 

Might want to triple check if it was the new model. The new models go one sale in store tomorrow.

 

I'm running Lion on the C2D 320M 13" and the animations are fine.

 

Oh, absolutely.

 

That would be even more concerning that the air is less powerful in the graphics department.

 

Lion on my 2010 13" MBA works great. No lags seen yet. Actually, dare I say this, Safari is snappier!

 

This is interesting. I doubt this would be CPU related. Maybe the GPU can't handle it or the APIs haven't been optimised for the hardware.

 

Aren't the new MBA's supposed to arrive in stores tomorrow only?

Unless, they got a first shipment with demos only, they're probably 2010 models since they wouldn't leave their MBA table empty for a full day just because new ones were announced.

 

Neither the 2010 or 2011 MBA has laggy animations or unusable Mission Control. Either the display model you failed to identify had a problem (or a backgrounded process eating up the system ressources, did you even check Activity Monitor ?) or you're outright just lying and causing panic for the fun of it.

 

People with 2010 base 11", how is Lion?

 

I had the 1.4 MacBook air but with 4gb and lion was as smooth as butter for me. Just sold it to pay for my 2011 version.

 

you remember if it had a backlit keyboard?

 

There's no need to be so harsh. I'm sure either the OP made an honest mistake, or there is another problem at hand. Either way, we really can't disprove OP until more consumers actually get some of these machines in hand.

 

The Air's in the NYC Apple 5th Ave store were the older 2010 Air's running Lion as of this morning.

 

Spotlight is re-indexing everything after the Lion install so expect a bit of lag until it's done updating

 

That's false. We can disprove the OP. Someone already did in this thread for the 2010 model and I'm sure we'd have heard something from the 13" MBP owners if Lion was unusable.

I did state in my post that the display model he used could have had a problem and he'd known if he had checked Activity Monitor. There was nothing harsh there, those are really the only 2 options here. Either we're dealing with someone out to bait a few replies and have fun or someone who didn't bother to check what was going on at all.

 

Those weren't the new Airs on Display...checked the same thing and they had the old Airs (with Lion) on Display...I do miss 3 finger dwiping back and forward on web pages though

 

They're still there, just change it from 2 finger to 3 fingers in the additional gestures panel, and they'll work again.

 

Do any of you air owners who have lion have an increased fan performance? Mine are running loudly with lion. Anybody else?

 

constant fan noise

yep, unfortunately I can confirm that (MBA 2010 13" 1,86 4GB on Lion). Fans are really bugging me out. Some said that this is due to 32-Bit Plugins/Browser extensions...

On SL I was quite fond of CoolBook - but that doesn't work with Lion as of now... waiting for an update

EDIT: apparently, the heavy indexing and the new 10GB Time Machine Backup drew a lot of Power. Still more fan noise than before.
