A touch tablet is a little big and downsizing to the iPhone has been an enjoyable experience.
It really irritates me when I send my clients documents for their review and all they have is a phone.
My macbook is now over ten years old and I can't download the newest versions of software any more, and stuff is starting to not work without those downloads. The mac has been my music recording/studio platform for ten years, and it was great having many multiple ports, both USB and analog, but the hardware has reached a dead end.
But I do have the newest iPhone and it comes with enough memory to take care of whatever garageband projects are coming up. Trouble now is lack of inputs so you have to go out and get a Roland piano/keyboard with bluetooth. Anything to justify getting another keyboard is cool in my book. :^)
