If you don't like iPads you probably won't like tablets. Hardware-wise they're all pretty much the same. The difference is really in software, and as far as software for showing photos and portfolios, there's pretty high parity between android and iOS. The Nexus 7 is a very nice device, and smaller than the iPad if that's what you're looking for, but as far as objective differences for this use case, it's not going to be all that different. Tough to match the newest iPad for resolution, so if you're concerned about IQ, it's probably your safest bet until October.
