just upgrated from Jaunty to Karmic w/out any problems

[Vitorio Okio]

I just wanted to share my experience upgrading from Jaunty to Karmic on 
Dell Latitude d820 with NVIDIA video and infamous Broadcom 4312 wireless 
cards. 

BTW, interestingly enough starting from Feisty I've never had any 
problems with my Broadcom card, while a lot of people complained. However 
with the release of Karmic the amount of complaints related to this card 
grew so much that I was quite scared to upgrade. 

Well, I've just upgraded without 0 (zero) problems. Everything worked out 
of the box as a charm.  I used it so far only for about an hour, so some 
problems might show up yet. But so far so good.

Though I must say about a much faster boot it's a falsehood as usual :-).

On my laptop with dual core 1.84 CPU and 1Gb of RAM it takes 60 seconds 
(it was 50 in Jaunty) from the moment I press Enter in GRUB menu to the 
Login Screen and then additional 15-20 seconds after I press Enter in 
Login Screen to full load.  That's pretty slow.  Shutting down is slower 
for about 5 seconds comparing with Jaunty as well.

Well, I guess I can leave with it.  Otherwise Karmic IMHO is quite a step 
forward.  Looks very, very nice.
