Gosh, whilst I understand the OP's thought's...I dislike shortcuts, and haven't bothered to memorise them either...I get by with a mouse...I even have a touchscreen laptop, and I don't really use this in Sonar either.
As for mastering and effects, huh?...Sonar is great for mastering, absolutely ****ing fantastic for mastering. The linear phase EQ for cleaning up master track, the tape and console emulator plugs for tone and gain control. I use Waves H-Comp for compression, but the ProChannel EQ set to pure is the bomb. I do use Waves Kramer Master Tape over the top before going into ProChannel's Concrete Limiter. This chain is the bomb. I know the OP's complaint was about the bundled effects, but it's a DAW...the effects that come with the program are bog standard. Honestly if you wan't WOW effects...check out the specials over at Waves...every weekend. In the last two months, I've picked up the Kramer HLS EQ and Pultec Eq for about 50 bucks Oz!! I also have Guitar Rig 4, which is a swiss army knife, and in particular I use it for all my delays, and flanger type effects.
Sonar does have a pad screen, however it's not's brilliant...but Sonar is not really designed for that particular paradigm. Try Bigwig or Live.
Does Sonar have issues...yes? Do other DAW's have issues...Yes?? Do other DAW's do everything bog standard out of the box, along with every ****ing plugin you could ever need or want?? NO!
Look I've complained in the past, however Sonar is about as good as it gets, it's not perfect but it works, it feels like a real studio environment.
