I used SPB shell on my rooted 596 but it was a little slow at times and with all the blur framework eating up memory, it was a bit less functional than I would like (when android killed it for memory, it took forever to reload). It was pretty good on ApeX 2 RC2, but it really runs quite well on CM7, since CM7 has no blur framework at all eating up the RAM. Also, root doesn't make it faster, but you can overclock which will. Also ApeX is faster than stock and CM7 makes stock look like Windows 3.1 by comparison.
Thanks all. I am waithing for Chevy to wok out the bugs on his SS then use it. Since it is built off of CM, it should be good. I hate to invest $15 in a launcher and not use it
It has improved quite a bit since day 1. It runs very smooth and fluid. I personally think it is a little heavy on RAM for our devices (4-5 times that of most launchers), but it does run well. The initial load each time does still take about 30 seconds to load, but if it gets killed by android, the re-draws are not as bad as on stock. Still a few second delay though. I like it, but I use a lot of apps, and I would rather have at least 768MB ram to run this, but that is just me. I am not saying by any means that it runs poorly, but I like to have 1-200MB "free" at all times.
