Interesting views here, and I guess much of it is personal.
There are plenty of e-mail harvesters around, but spamming is all around us. Managing it is the key, so I don't mind giving out a gmail address because google is good at sorting my garbage out!
As for my credentials, I'm an Android freak, owning a Galaxy Note and looking at getting a 10.1 tablet so - you guessed it, I'm your target audience.
My first response was.... why 7inch? Your site includes tablets of all sizes and I guess you'd be a bit limited so .... I can't figure that out.
Header image - meh... didn't really get my juices going - perhaps introduce a more graphic image like the one at
http://i.telegraph.co.uk/multimedia/archive/02229/iPad-Rick_2229235b.jpg - not that one - but one like it to add a bit of intrigue and style.
The main rollover images are distracting - only because they are different heights and everytime it switches, the whole content shifts up or down to compensate.
Nevertheless, I did start reading up...
You know what... I read lots of reviews and your reviews are OK - but its all a bit text-heavy. When I'm going over the web to fact-find, I like nice obvious comparison tables and graphics to illustrate unique selling points.
For instance, having a small table at the top of each review stating: size, manufacturer, battery life, core, resolution - maybe with little icons for each ...... oh yeah - then I can judge quickly what I want to start reading.
I think you just need to think about what sells a tablet and ram it down your viewers throats - not just in a blog-format.
Hope this helps a bit.
