Advice needed for gorgeous bag

[Atwaroverscrabble]

ok.... I am nearing the end of my phd (i hope!) and i have decided to save up and treat myself to an almost forever bag as a congratulations to myself!

Question is, what should i get? I am hopeless at getting bags, i basically need a nice big bag into which i could fit a netbook, a5 diary, small clutch/mini bag with money and a small make up bag... This is for when i hopefully work as a lecturer so need to take stuff in but not necessarily carry the big bag all day...

I'd like leather, colour i am open to suggestion....

So guys, any suggestions?

Is this too big? -- Love these bags but not for everyone.

This was pricey but is on sale at the moment nice colour for the Autumn. Think you would get A4 size into both of these most bags narrow at the top making it difficult to do that.

Ooh they all look lovely, thank you... No bag is too big!

What's your budget?

I think i could probably save up to £150.... I would quite like a lovely fountain pen too out of that
